This article is about the electronic device. For the Microsoft Windows Software, see CD Player (Windows).

A Compact Disc player (often written as compact disc player), or CD player, is an electronic device that plays audio Compact Discs. CD players are often installed into home stereo systems, car audio systems, and personal computers. They also manufactured as portable devices. Modern units support other formats in addition to CDs, such as DVDs, CD-ROMs with audio files and video CDs. DJs often use players with an adjustable playback sampling rate to alter the pitch of the music programme. Many modern CD players also play MP3 CDs. CD playback functionality is available on all modern CD-ROM/DVD-ROM drive equipped computers as well as on DVD players and CD-ROM/DVD-ROM based game consoles.

Many CD players are contained in a plastic and steel casing which also houses the electrical system and the user interface. The housing of a portable CD player also contains ports used to connect the player to a powered or unpowered speaker, headphones and/or a power system (see electrical wiring in the United States or in the UK). A portable CD player generally contains an internal power source in the form of batteries. The housing of a stand-alone CD player contains speakers and perhaps a radio and/or tape deck. CD players used in component audio systems contain a power source, the user interface, and numerous ports to connect the player to the various parts of an audio system.

In 1982 utilising a slide-out tray design for the CD. As it was easy to use and manufacture, most CD player tray designs had followed this style of tray ever since. However there have been some notable exceptions.

By Sony at the Japanese Audio Fair in 1982, Sony showcased the vertical loading design of the CD player. Although the prototype's design was never really put into actual production, it was for a time adopted for production by a number of early Japanese CD player manufacturers including Alpine/Luxman, Matsushita under the Technics brand, Kenwood and Toshiba/Aurex. For the early vertical loading players, Alpine sourced their AD-7100 player designs for Luxman

In 1983, at the US and European launch of the CD format, Philips with their CD100 CD player (sold as Magnavox in the US), showcased the first top loading CD tray designs. The design had a clamp on the lid which meant the user had to close this over the CD when it was placed inside the machine. Apart from having no motors accessing a movable tray, thus interfering with the player's sound quality, as the disc was clamped right down within the player, it implied better sound quality. This was one of the primary reasons manufacturer Meridian created their MCD CD player,

Whose chassis design was derived from the Philips CD100. Apart from being adopted on various stereo equipment designs such as mini components, over the years only a handful of hi-fi quality top loading tray CD players had been made. The most notable were Luxman's D-500 and D-500X series

Meridians 200 and 203 players were the first players to adopt tray loading with sliding play mechanism. Basically as the tray came out to collect the CD, the entire player's transport system also came out as one unit. The players were also the first to utilise the CD Transport design whereby the audio electronics were separate from the CD drive mechanism itself to reduce jitter and distortion.

A few companies produced CD players with dampened trays. The dampers were rubber grommets built into the tray to reduce distortion. Yamaha's CDX-1000 CD player was a good example of this design.

Slot loading is the preferred loading mechanism for car audio head units, the Apple MacBook, Playstation 3, amongst other audio players. There is no tray that pops out, and a motor is used to assist disc insertion and removal. Mini-CDs and non-circular CDs may have troubles with insertion and/or ejection.

The radial mechanism, designed by Sony to avoid using Philips patent, which is the one used in most CD players nowadays (because it is cheaper) - the lens moves on a radial rail. It is also known as 3-beam linear tracking.

A CD player has three major components. a drive motor, a lens system, and a tracking mechanism. The drive motor rotates the disc between 200 and 500 revolutions per minute. The tracking mechanism moves the lens system along the spiral tracks in which information is encoded, and the lens reads the information using a laser beam, typically produced by a laser diode. The laser reads information by focusing a beam on the CD, which is reflected back to a sensor. The sensor detects changes in the beam, and interprets these changes to read the data. This data is output as sound using a digital-to-analog converter (DAC). A subcode in an audio CD contains information on the total number of audio tracks, the running time on the CD, running time of each track, and other information. This information allows the drive motor to speed up or slow down as needed to read data at a constant rate.

The interface of a CD player does not vary widely from manufacturer to manufacturer. It is usually composed of a few buttons and a display device. Common buttons include play, pause, stop, advance/fast forward, back/rewind and, in the case of a multiple-CD player, disk selection. The display may provide information such as track number, track time, disk number in the case of multiple-CD changers and CD-Text.

Prior to real CD changers being introduced, an attempt was made to copy the double cassette players found in many audio systems. As a result, devices with two separate, fully functional CD players were made. Very few cassette changers were produced, mainly because a double-cassette deck could copy from one cassette to another. Double-CD decks, on the other hand, did not have this copy functionality since recordable CDs were not commercially available. Therefore, the shift to changers was swift, removing the need for double CD players.

External cartridge CD changers have one or more cartridges that the user loads with up to 12 different CDs (depending on manufacturer) and then inserts into the CD changer. The CD changer can then remove one CD at a time for playing. This type of player is commonly found in vehicles because the user can switch easily between large amounts of media contained in different cartridges.

Internal cartridge CD changers work on the same basic principle as external cartridge players, except the cartridge never leaves the CD player. This type of CD player accepts multiple CDs through a single slot and stores them internally.

A carousel type CD changer consists of a circular platter that holds three or more CDs. Traditional carousel CD players hold three, five, or seven discs on a flat carousel tray. The carousel ejects to allow access to the CDs. Once back inside, the CD changer can rotate the carousel to access all of the CDs. Such carousel CD changers often allow the user to rotate the carousel while open, and change all CDs if no CDs are currently playing, or to eject the carousel while one CD is playing to change any CDs accessible from that position. Another type of carousel CD player is the mega-disc or "jukebox" CD players as they are also known. They usually hold anywhere from 50 to 300 discs. The mega-disc CD player holds its discs in a vertical position in slots that located 360 degrees around the carousel. When a disc is selected to be played, the carousel rotates so that the disc can be picked up by a pickup mechanism and placed in CD playback unit. Mega-disc CD players generally have a means of entering in titles of the CDs stored inside them, such as telephone style letter input system found on the remote control, a full letter keypad on the unit, or by use of an external keyboard attached to the unit. Many units can also automatically obtain the title of a CDs if it contains CD-Text info stored on it.

Digital audio players have surpassed the concept of CD changers. For example, the first generation iPod can hold an equivalent of 50 discs (1000 songs)

With a 128k bit rate for each song. thereby, the iPod is 1/10 the size of a CD changer cartridge, and about 1/20 the size of a carousel changer. Solid state flash-based digital audio players have rendered compact discs and thus CD changers obsolete for some purposes. While digital audio players often use a lossy compression scheme, they usually can accept lossless formats such as WAV (PCM) as well, matching the quality of CD audio.

CD Players/Recorders Buying Guide Despite the popularity of Mp3 players, iPods etc, CDs are still the dominant form for the way we listen to our music. They've been around for quite some time, some companies have tried to replace them with other technologies but have failed, let's face it, CDs are here to stay for some time to come. There are any types of CD players and CD recorders out there on the market today, they range from basic inexpensive models to fully featured, and rather expensive ones from several companies. The fact that many companies are still producing them and even coming out with newer versions just goes to show that CDs aren't going anywhere anytime soon. There are two basic type of CD players out there Single-Disc and Multi-Disc, they're basically the same thing really, just as their names suggest, one is use for single CDs and the other can hold multiple CDs for you. When it comes to features, usually the basic feature set of both types is the same. Single disc CD Players though are becoming more of a rarity since most DVD players can play CDs, so most people will opt for the DVD player version to have both abilities in one device. Built-In Features. Just like your portable CD player or in-car player, with stand alone CD Players you've got the ability to do quite a few things, but of course the stand alone versions do offer a bit more options to the end user. Play Intro. I'm sure everyone knows what this is, it's the ability to play a few seconds of each song on the CD, this is great if you don't know the name of the song you want but know what it sounds like. Repeat. This one is self-explanatory, it allows you to repeat a song, but some players allow you to select certain songs to have repeated, if this is an option you use make sure to check to see what kind of repeat the player you want is supported. Random or Shuffle. This is also very self-explanatory, hew player will just randomly play songs from the discs or discs inside. Custom Programming. This more refers to multiple disc players, but some will let you customize playback with discs or songs. MP3 Compatibility. Some CD players will have the ability to play MP3s as well as standard CD audio, but not all. So if you desire this ability make sure it can do it. Remote Control. Most all will come with a remote control, but you want to look for one that is easy to use, and has the most often used buttons in an easily accessible place. You'll also want to check to see if the remote supports or controls the features you want it to. Some can also come with a back light as well which is great for when you're playing music in the dark, you won't be fumbling around trying to figure out which button is which. Outputs. You can have several types of outputs on CD players, like digital, coaxial, or optical, what you'll specifically need will depend on your existing setup. Inputs. Some players will come with inputs as well, and this usually pertains to CD Recorders specifically but CD players can have them too. Just like the outputs, you can find several types of inputs as well. Headphone Jacks. Most players will come with at least one headphone jack, but many can come with two so if you wish to share your music make sure the device has more than one jack. Other Features. Depending on what you need there are other features you might be interested in like Tempo Change Functions, Pitch Control, Built-in Microphones, External Microphones, Speed Controls, built in Equalizer and many other choices. Of course the more advanced features you need the more you'll most likely end up paying for a product. Most of those features listed are available on high end and professional use units, but sometimes you can find them on lower end units as well. Some units, especially the multiple CD players can come with keyboard inputs so you can hook up a standard keyboard to it to help you input information about the discs easier. This is a very nice feature that makes inputing information much easier. CD Recorder Specifics. CD Recorders will have the same features as CD players normally but there are added things that you can find on them. Hard Drives. There are many CD recorders available with integrated hard drives so you can rip your music to it and listen that way, or burn from the hard drive to a CD. Editing. Some recorders have editing features built in, like creating table of contents, titles and projects. Compatibility. Most recorders will record to CD-Rs, but some will also record and erase CDRWs as well so you can keep using the same CD over and over, as your music tastes or favorites change you can just change the disc to suit your needs. This is a great feature to have, but remember though not all players can read CDRWs, so if this is an appealing option make sure what you want to play you homemade discs on can read CDRWs. Speeds. Just like the CD/DVD drive in your computer the speeds of the drives in stand alone CD Recorders will vary by price, model and manufacturer. If speed is something you desire then you'll want to check for the speeds of both CDRs and CDRWs in the specs section of the product. As with any product the one that you choose will be specific to your own needs, look around and decide what features you need and will use most. While having the ability to hook a keyboard up is nice, if you only use the feature once or twice is it really worth the added cost? When you're deciding on a product always check out the features and specs to see if it's what you want and need, and one that will work with your existing system. If possible go and see the unit in person, see how easy it is to use, and how well it is made. Seeing the unit in person isn't always an option so the next best thing is places like TestFreaks that have comments from actual users who own the products, end consumers can tell you a lot about a product and how well it works. Of course check online and even offline in audiophile magazines as well for reviews of products, here you can learn quite a bit, they've usually got many detailed pictures and of course their opinions of the products and how they work.

If you are registered to take a Language Test with Listening you must bring an acceptable CD player to the test center for use on the listening portion of the test.

Make sure your CD player is in good working order. Insert fresh batteries the day before the test. You may bring additional batteries and a backup player to the test center. Test center staff will not have batteries, CD players, or earphones for your use.

If the volume on your CD player disturbs other test-takers, the test center supervisor may ask you to lower the volume or move to another seat.

Advantages. small, good model Disadvantages. nothing.realibilty! When you purchase a SONY Model Items, you are purchasing a realibilty product, a product that you can make sure that you are buying a real and honest model. SONY that is known well around he world is well known for its good reputatation. SONY has many items, such as DVD's, TV's and more. Sony has also the well nows playstation that is a very good product. THIS CD Player with a build in radio and also mp3 playback is good. Good laser.

Advantages. Small, compact, volume control on earphone wire, cool design, 45 second anti-shock Disadvantages. flimsy latch on lid, appalling battery life.the moment you buy the Philips AX3301. It starts off well enough - the unit is very well designed, the display although small is clear enough, the controls nice and easy to use / find, sound quality is fine. There are even some nice touches for the price such as the volume control remote on the earphone wire (useful if you have your player in a case or in your bag and someone starts talking to you!), and also the dual-battery type holder - use..power?), but I wasn't prepared to risk it and so went with a Sony D-NE511 (also reviewed) - the difference is amazing - hello 85 hour playback times!!! Sorry Philips but either your product or your quality control sucks. I'll not risk your CD player products in future..

Portable Compact Disc Players were first introduced in the 1980s, but weren't predominant until the 1990s. At first, most people thought of personal CD players to be no more portable than a cassette player. Also, since they had no anti-shake feature, they couldn't really be used in a portable manner. However, when companies introduced Electronic Skip Protection in around 1993 to minimize the CD skipping associated with active use, the portable CD player truly became portable. After that refinement, most people used CD players rather than cassette players.

Portable CD players have been predominant for years, and have boosted many electronic companies' success, namely Sony's. But since digital audio players were introduced, the popularity of CD players has decreased. CD players are still being made, but many newer players have MP3, WMA, and CD-R capabilities to keep sales up. Thinness is also a big factor. Models are getting thinner and smaller with each revision. As adding more seconds of anti-skip memory is expensive, MP3 players are a preferred choice for environments where physical shock persists (e. g. off-road, jogging, etc.).

(02/15/2008) I have been using this player for about a year and I find it to be a very convenient player with all of the bells and whistles and then some. I am currently using the CD-1700 with a Korg Zero 8 mixer. Whatever the mixer wont allow, the CD-1700 has it covered. The sampling is on point with looping on CD's is a must have. the time mode display is also versatile, allowing you to display remaining time or track time. This unit has a nice pitch function as well with a tempo change button along with a + and - bend range from 0 to 160 with a tap temple button. Cue and play is almost instant, cue also have 3 storage points. Also this unit plays CD-RW and CD'MP-3 and have additional effects such as echo, flanger, filter along with synchronizing the effect with the BPM. what more could you ask foe on a cd player?

Audio CD player/recorders cost more than CD players without recording capability, but prices are dropping. They sell as stand-alone units and as components of some minisystems. There's another way to make your own music CDs. Record them using a computer. CD drives that burn CDs are now standard on many computers and can be as adept as component CD player/recorders, often performing the task more quickly. But component CD recorders allow you to easily record from other components in your sound system--such as a tape deck, radio, turntable, or TV set. They're the most convenient way to convert a collection of vinyl LPs to the compact disc format, for example. Both CD player/recorders and computer CD burners let you copy entire discs or dub selected tracks to create your own CD compilations. There's no quality lost in high-speed CD-to-CD dubbing. Recording speeds usually are real-time or 4x, which records in one-quarter of that time. (Computer CD burners can be as fast as 16x.)With either approach, you can record to CD-Rs (discs that can be recorded on only once) or to CD-RWs (rewritable discs that can be erased and rerecorded). CD-Rs play on almost any CD player, whereas CD-RWs generally play only on newer disc players that are configured to accept them. Be aware that some older DVD players may have problems reading CD-R and CD-RW discs.

Audio CD player/recorders are sold by audio-component companies such as JVC, Panasonic, Philips, Pioneer, and Sony. Dual-tray models. One tray is for play/record, another for play. Price range. $130 to $700.Changer models. These typically hold four or five discs and allow you to change the discs while one is playing. Price range. $200 to $1,500.Computer CD burners. A CD-recording drive in a computer lets you copy other CDs or download music from the Internet and record it on CD. Price range. Standard with many new computers. A drive can be added to older computers for about $100, including software.

With CD recorders, you program your selections from discs loaded in the changer. the steps will be familiar to anyone who has programmed a CD changer. Most units give you a running total of the accumulated time of the tracks as you are programming them. The computer approach to burning CDs makes compiling "mix" discs easier than it used to be. Once a blank CD is inserted into a computer CD drive, the accompanying software displays a track list from the source disc and allows you to "drag" the desired tracks into the lower panel. As you insert successive CDs, you can see the playlist for your CD-to-be and even change the order of the tracks, combine two or more tracks or files into one, or split a track or file into two or more. With both the CD player/recorder and the computer option, you must program selections from each disc in succession. Defining tracks on the CD onto which you're recording is accomplished with varying degrees of flexibility. How many track numbers a given player/recorder can add per disc, for example, differs from one model to another. Additionally, assigning track numbers when you're recording from cassettes or LPs may be automatic or manual. (Such track numbers are inserted automatically when recording from CDs.) Text labeling, available on some models, lets you type in short text passages, such as artist and song names. This is a much easier procedure with a computer keyboard than with a console's remote control. The number of delete-track modes gives you flexibility, whether you need to delete one track or the entire disc. One-track, Multitrack, and All-disc are three common modes. An audio CD player/recorder typically has three playback modes. Program, which plays tracks in a specific order. Repeat. and Random Play (or Shuffle), which plays tracks randomly. Connection types can affect which external sources you're able to use to make a CD. A digital input jack may be optical or coaxial. An analog input jack lets you record your tapes and LPs. A microphone input offers a low-cost way for home musicians to make digital recordings of their performances. A record-level control helps you control loudness while recording digitally from analog sources--a problem you don't face when recording from digital sources.

Decide between an audio CD recorder and a computer drive. Either method of burning a CD--using an audio CD player/recorder or a computer--makes a recording that's audibly (even electronically) indistinguishable from the original CD. Audio CD player/recorders excel in versatility. you can record from virtually anything that you can connect to a sound system's receiver. The computer method affords a connection to the Internet, so you can burn downloaded MP3-encoded files onto CDs, as well as record music from CDs. A computer offers more set-up choices when you're assembling a CD from several prerecorded discs. And, when you're recording from analog sources, the computer's CD-burning software often includes sound processing that will reduce the snap and crackle of a vinyl LP or the hiss of a cassette tape. However, connecting a turntable or cassette deck to a computer requires additional equipment. If you don't already have a CD-burning drive in your computer, you can add one. A CD-RW drive is standard equipment on many new computers. If you want an audio unit, get a multidisc changer rather than a single-disc player. The relatively low cost of burning high-quality CDs makes CD recording a good alternative to making cassette tapes. If you're buying a CD player/recorder, a changer has advantages over a single-disc model and needn't cost much more. Its multidisc magazine or carousel will make it easy to record compilation CDs or to play uninterrupted music.

Introduction The format war for high-definition discs wages on, but for now, DVD is still the reigning king of home video formats. We all have years of back catalogue DVDs in our collections, and a solid player is of paramount importance to any theater. High-resolution audio in the form of SACD and DVD-Audio are still prominent and Denon makes several levels of players capable of spinning CD, DVD-Video, DVD-Audio and SACD discs, with their top of the line spinner being the DVD-5910CI priced at $3,800. The DVD-5910CI is designed to be the primary source for a high-end home theater or whole home distribution system and, as such, offers connectivity not often found on consumer level goods. The CI stands for Custom Integration. This is Denons way of identifying their products with connectivity and control features for home integration and theaters using advance control systems. This flagship DVD player in the Denon line offers a vast array.

Introduction Believe it or not, the market for high-end CD players is alive and well. Despite the introduction of new high-end formats such as DVD-Audio, SACD and now HD-DVD and Blu-ray, the fact remains that there is more music available on CD than on all the new high-resolution formats combined. The music lovers who have a large collection of music on CD still need high-quality players in order to fully enjoy the music that they have spent so many years amassing. The CDP-202 ($6,500) is the latest and greatest of the stereo-only CD player options in Classs Delta series of products. The Delta Series is the first new product series from Class Audio since Class became part of the BW group. I place CD player in quotes when describing the CDP-202, as it will actually play just about any non-high-definition disc format other than SACD. The new Delta Series CD player screamed well-made high-end.

Introduction When Lexicon first introduced the RT-10 Universal Disc Player in 2003, it was considered by many an ambitious project. Subsequently, the Proceed Audio brand was discontinued and the Harman Specialty Group (HSG) was formed. Harman International formed HSG on the cornerstone of three key brands. Mark Levinson, Lexicon and Revel. The RT-10 would be scrutinized by home theater industry experts and consumers alike, not only because it was HSGs first foray into source componentry the Mark Levinson brand did not and still does not manufacture a video source component although the No. 51 will be available soon but also because it came on the heels of Proceeds $6,000 PMDT universal transport, which had a litany of reliability issues until it was eventually discontinued. In addition, Lexicon would enter this high-stakes reference-quality segment of the market by designing the RT-10 as a hybrid player featuring two new technologies. Super Audio CD (SACD) and DVD-Audio.

Introduction My audio/video system has changed dramatically over past couple years. A while back, my rack consisted of a CD player, SACD player, DVD player, VHS deck, preamplifier, surround sound processor and several power amplifiers. Of course, then there were the miles of cable it took to hook the endless string of components together. Not to mention the remotes. But that was then, and this is now. Todays modern audio/video enthusiast has options, like receivers and universal disc players, which over the years have made huge strides in quality and performance, leaving a lot of the traditional solutions in the dust. Enter Denons 3910 single-disc, DVD-A/SACD Progressive Scan Universal Disc player, a source component that literally plays everything. One player, multiple formats. what could be better? I have been on the lookout for a good universal player for several months, because Ive just had it with maintaining multiple players. Luckily Denon, as well as other manufacturers,.

Introduction The world of ultra-high-end audio has had to adjust their business model quite a bit over the last decade. With technology developing in new and exciting ways, equipment manufacturers clamored to produce real-world digital products that would support the new emerging software formats when, historically, high-end audio was an industry based around excellence more in analog (preamps, amps, speakers, turntables) products. While most of the high-end equipment manufacturers steered clear of machines that supported future and uncertain formats, Linn Products, a company known for taking bold and adventurous steps in the name of uncompromised sound, took new audio formats for music and movies as a challenge. Not surprising, considering that Linn produced and sold, very successfully I might add, one of the worlds best and most expensive dedicated CD player at $20,000. Linns solution to the ever-growing need for a universal high-end player, which can unite all aspects of optical disc playback, is the Unidisk 1.1.

Turntable The optimum use of a disc record of constant rotational speed occurs when the innermost recorded diameter is half of the outermost recorded diameter.

The popularity of this unit was due in no small part to its portability, but also to its suitcase-styled finishing touches that became a Crosley hallmark.

Advantages. Great device with inbuilt radio. Does the job efficiently Disadvantages. Small inbuilt memory capacity The NAD CD Player should not be frowned at! With a price tag of around £160 and an attitude that says 'Use me', this device is one for the amateur to the professional music listener. The NAD comes complete with a full working order built in radio that connects digitally to your favourite stations. There is an MP3 Playback option that gives the user more freedom in concern with the more modern forms of media. It must be noted that the NAD houses an..stored internally. This storage is limited however. Being an older model from 2007, its capacities and uses are withdrawn to that of similiar models, but if your wanting a reasonable CD player with several inept inbuilt functions and ease of use, this is the one for you. You must also take into account that the CD Player is not shock proof, so if used, it is recommended to plug it into an anti-surge socket extension (for peace of mind). I hope.

Advantages. Its cheap and plays well Disadvantages. may not work with every amplifier.CD player CDP-XE370 CD from Sony which i bought a few months ago, wasn't a mistake at all. Its beautiful and light weight, plays with good tonal balance and has a very good resolution. Its just fit in some space i was keeping for it close to my Kenwood Stereo Amplifier KA 770 D that gives her a real good stereo mix quality and dynamic sound like that of a 300pound CD player. Its worth the price and quality. The ease to carry it about and its good.

Unless you have some unexplained obsession with gadgets of yesteryear, you probably haven't been paying close attention to how many brands of portable CD players your local retailers have been stocking. According to Currys over in the UK, however, it's being pressured to order up truckloads of 'em to satisfy the 50 percent uptick in demand compared to last year. Moreover, John Lewis (a department store) has begun stocking the units again some four years after originally putting them to rest. Analysts are asserting that the lagging economy is leading people to select these devices as stocking stuffers, with their ease-of-use and rock-bottom prices making them highly attractive in the current market. Word to the wise, though -- chances are that special someone would much prefer a low-end 1GB DAP over something they probably already have. Or, you know, a

Come on seriously whats the point mp3 player are not that expensive. I would rather use a low end mp3 player than to go backwards and use a cd player.

CD players may be old stuff but they still produce better sound quality than the average MP3. Until FLAC or a similiar lossless standard becomes the norm they probably still have a place in the market.

Cds sound better. But you are talking about a portable player with tiny crappy speakers, Even those $500 headphones sound like crap compared to $30 regular speakers. It's like all that people that love how their vinyls had that natural sound with the added scratches. I guess there will always be a market for everything.

I think I want a portable record player for x-mas. It's the only real lossless media form. Analog sound waves FTW!

I can't tell the difference between 320kbps MP3's and lossless, or CD audio. But I *can* tell the difference on the audio output of both my Creative Zen, and an iPod Touch, and neither compares to what I get from a 6 year old Sony Walkman that only plays cd's. Mind, it cost about twice what other cd players cost at that time, when they were starting to be phased out of the market, so it ought to be good. But it surprises me mp3 players still haven't caught up. Of course, this is all in the ear of the beholder, as it were.

Eh, don't get all worked up about my comment. I'm not an audiophile although I do have an appreciation for higher quality components and recordings. I was just commenting on the article since it seemed to be dismissing CD players as old and useless tech. My point is that it's something that can play CDs which are uncompressed and better than MP3s. I'd rather buy a CD than MP3s. At least if you convert the tracks to MP3 you still have the untouched copy. With MP3s you're purchasing something that has already been degraded.

Now, the Burr-Brown decoding chip in my receiver might be able to tell the difference. But as long as we're talking portable, there's no sense in saying that you need FLAC or lossless audio tracks. Plus with flash storage prices ever on the fall and with flash being so much more stable, i. e. no buffering.a 1 or 2GB flash player makes more sense to me.

I actually had (and have still got) the CD player Engadget have used in the article, might even whip it out the loft for old times sake =]You never know either, the headphones could be better then Apple's standard ones too.)

Might I also add how scary technology (and size) has evolved, take one of these CD players, a maximum of 700MB CDs and the best place to put it if you was on the move was in the backpack/rucksack. On the other hand look at the iPod shuffle, 2GBs worth of space (higher-end wise) and it's half the size of a matchbox.

Ridgecity. I'm confused, why are you talking about speakers? I am comparing CD audio to MP3 audio which is compressed. Wwhat. Sorry to break it to you but Ipods aren't exactly praised for their superior audio quality. That doesn't matter though because if you're playing an MP3 file you're playing a file that has been compressed and has lost quality. So, even if the Ipod had superior sound quality it would be wasted on a lossy file. MP3 players that offer better sound hardware are generally able to play FLAC because it would actually be useful.

I hook up a portable CD player to my decent set of speakers instead of my iPod or PC. The sound is superior, and its definitely noticeable on a decent set of speakers. Really though, how has the economic crisis got this bad to the point where people are buying these to replace the convenience of a 1gb DAP? The difference in price is maybe £10?

Nicholaelaw, yes, and then you stick it into the cd-drive of your computer and it magically turns into a file us. of course maybe some people do not know how to change the setting to apple lossless in iTunes, or even know how to use iTunes, or even have a computer. That would explain the reason people would want a cd player, not because of anything to do with audio quality.

I still use my CD player from time-to-time. I may still buy music from iTunes, but when going for uncompressed stuff and for bands and musicians I'm a big fan of, buying a music CD of theirs is much better. Or, it could be the music fan in me.

Ive still got my portable cd player in the cupboard, i think i bought it 5 years ago..im SO glad we have moved on from that, optical media is the worst. Durability is a MAJOR problem, along with read and write speeds. I really cant believe theres been a resurgence. I also really cant believe the recording industry hasnt looked into other standards to sell music (other than..what was it..those sandisk micro cards)

I work in John Lewis too and I haven't seen any portable CD players as yet O_o maybe they'll turn up soon..I can see why they're resurfacing again, but I personally prefer ripping the CDs and just having them as a backup in case the songs are deleted from my phone/mp3 player.

We use an old Sony CD Walkman at work, we just connect it though a Hi-Fi to amplyfy the sound - reason being is that the Hi-Fi doesn't playback MP3 files and the Walkman does but also the battery life on these things is insane if you're just playing MP3 CD-R's, we get around a week out of every charge of usage (probably around 35 hours playback time), sure we can only get 700MB of data into this thing but there are still no MP3 players as far as I am aware that can go for so long.

In Australia, portable CD players are very easy to find and are often at reduced prices around this time of year. I've seen plenty of Sony CD Walkmans for sale in some stores-usually at "JB Hi-Fi" and at Target & Kmart stores-basic model is the D-EJ011 in Australia and goes for about $49, MP3 playback model is NE240-$80. I have also seen Jensen and SONIQ models too-around $28-$39. And at thrift stores too-like a D-181 for $1 (10 years old model but still good quality). Sony has not updated its range of portable CD players since late 2006 though. And I always have found these to be good sounding-the Sony players are very good with a bass boost called "MEGA BASS" enabled.

The first album to actually be released on CD was Billy Joel's 52nd Street, that reached the market alongside Sony's CD player CDP-101 on October 1, 1982 in Japan.

Early the following year CD players were released in the United States and other markets. This event is often seen as the "Big Bang" of the digital audio revolution. The new audio disc was enthusiastically received, especially in the early-adopting classical music and audiophile communities and its handling quality received particular praise. As the price of players sank rapidly, the CD began to gain popularity in the larger popular and rock music markets. The first artist to sell a million copies on CD was Dire Straits, with its 1985 album Brothers in Arms.

Diagram of CD layers. A. A polycarbonate disc layer has the data encoded by using bumps. B. A reflective layer reflects the laser back. C. A lacquer layer is used to prevent oxidation D. Artwork is screen printed on the top of the disc. E. A laser beam reads the polycarbonate disc, is reflected back, and read by the player.

Scanning velocity. 1.2–1.4 m/s (constant linear velocity)– equivalent to approximately 500 rpm at the inside of the disc, and approximately 200 rpm at the outside edge. (A disc played from beginning to end slows down during playback.)

The program area is 86.05cm² and the length of the recordable spiral is (86.05cm²/1.6µm)=5.38km. With a scanning speed of 1.2m/s, the playing time is 74minutes, or around 650MB of data on a CD-ROM. If the disc diameter were only 115mm, the maximum playing time would have been 68 minutes, i. e., less six minutes. A disc with data packed slightly more densely is tolerated by most players (though some old ones fail). Using a linear velocity of 1.2m/s and a track pitch of 1.5µm leads to a playing time of 80minutes, or a capacity of 700MB. Even higher capacities on non-standard discs (up to 99 minutes) are available at least as recordables, but generally the tighter the tracks are squeezed, the worse the compatibility.

The smallest entity in a CD is called a frame, which consists of 33 bytes and contains six complete 16-bit stereo samples (two bytes × two channels × six samples. equals 24 bytes). The other nine bytes consist of eight CIRC error-correction bytes and one subcode byte, used for control and display. Each byte is translated into a 14-bit word using eight-to-fourteen modulation, which alternates with three-bit merging words. In total there are 33 × (14 + 3) = 561 bits. A 27-bit unique synchronization word is added, so that the number of bits in a frame totals 588 (of which only 192 bits are music). These 588-bit frames are in turn grouped into sectors. Each sector contains 98 frames, totaling 98 × 24 = 2352 bytes of music. The CD is played at a speed of 75 sectors per second, which results in 176,400 bytes per second. Divided by two channels and two bytes per sample, this results in a sample rate of 44,100 samples per second. For CD-ROM data discs, the physical frame and sector sizes are the same. Since error concealment cannot be applied to non-audio data in case the CIRC error correction fails to recover the user data, a third layer of error correction is defined, reducing the payload to 2048 bytes per sector for the Mode-1 CD-ROM format. To increase the data-rate for Video CD, Mode-2 CD-ROM, the third layer has been omitted, increasing the payload to 2336 user-available bytes per sector, only 16 bytes (for synchronization and header data) less than available in Red-Book audio.

The largest entity on a CD is called a track. A CD can contain up to 99 tracks (including a data track for mixed mode discs). Each track can in turn have up to 100 indexes, though players which handle this feature are rarely found outside of pro audio, particularly radio broadcasting. The vast majority of songs are recorded under index 1, with the pre-gap being index 0. Sometimes hidden tracks are placed at the end of the last track of the disc, often using index 2 or 3. This is also the case with some discs offering "101 sound effects", with 100 and 101 being indexed as two and three on track 99. The index, if used, is occasionally put on the track listing as a decimal part of the track number, such as 99.2 or 99.3. (Information Society's Hack was one of very few CD releases to do this, following a release with an equally-obscure CD+G feature.) The track and index structure of the CD carried forward to the DVD as title and chapter, respectively.

Compact Disc + Graphics (CD+G) is a special audio compact disc that contains graphics data in addition to the audio data on the disc. The disc can be played on a regular audio CD player, but when played on a special CD+G player, can output a graphics signal (typically, the CD+G player is hooked up to a television set or a computer monitor). these graphics are almost exclusively used to display lyrics on a television set for karaoke performers to sing along with.

Compact Disc + Extended Graphics (CD+EG, also known as CD+XG) is an improved variant of the Compact Disc + Graphics (CD+G) format. Like CD+G, CD+EG utilizes basic CD-ROM features to display text and video information in addition to the music being played. This extra data is stored in subcode channels R-W. Very few, if any, CD+EG discs have been published.

Super Audio CD (SACD) is a read-only optical audio disc format aimed at providing much higher fidelity digital audio reproduction than the Red Book. Introduced in 1999, it was developed by Sony and Philips, the same companies that created the Red Book. SACD was in a format war with DVD-Audio, but neither has yet managed to replace audio CDs. In contrast to DVD-Audio, the SACD format has the feature of being able to produce hybrid discs. in addition to the SACD audio, these discs contain a standard audio CD layer which is playable in standard CD players, thus making them backward compatible.

Video CD (VCD, View CD, and Compact Disc digital video) is a standard digital format for storing video media on a CD. VCDs are playable in dedicated VCD players, most modern DVD-Video players, personal computers, and some video game consoles. The VCD standard was created in 1993 by Sony, Philips, Matsushita, and JVC and is referred to as the White Book standard. Overall picture quality is intended to be comparable to VHS video. Poorly compressed VCD video can sometimes be lower quality than VHS video, but VCD exhibits block artifacts rather than analog noise, and does not deteriorate further with each use, which may be preferable. 352x240 (or SIF) resolution was chosen because it is half the vertical, and half the horizontal resolution of NTSC video. 352x288 is similarly one quarter PAL/SECAM resolution. This approximates the (overall) resolution of an analog VHS tape, which, although it has double the number of (vertical) scan lines, has a much lower horizontal resolution.

Super Video CD (Super Video Compact Disc or SVCD) is a format used for storing video media on standard compact discs. SVCD was intended as a successor to VCD and an alternative to DVD-Video, and falls somewhere between both in terms of technical capability and picture quality. SVCD has two-thirds the resolution of DVD, and over 2.7 times the resolution of VCD. One CD-R disc can hold up to 60 minutes of standard quality SVCD-format video. While no specific limit on SVCD video length is mandated by the specification, one must lower the video bit rate, and therefore quality, in order to accommodate very long videos. It is usually difficult to fit much more than 100 minutes of video onto one SVCD without incurring significant quality loss, and many hardware players are unable to play video with an instantaneous bit rate lower than 300 to 600 kilobits per second.

Photo CD is a system designed by Kodak for digitizing and storing photos on a CD. Launched in 1992, the discs were designed to hold nearly 100 high quality images, scanned prints and slides using special proprietary encoding. Photo CD discs are defined in the Beige Book and conform to the CD-ROM XA and CD-i Bridge specifications as well. They are intended to play on CD-i players, Photo CD players and any computer with the suitable software irrespective of the operating system. The images can also be printed out on photographic paper with a special Kodak machine. This format is not to be confused with Kodak Picture CD, which is a consumer product in CD-ROM format.

The Philips "Green Book" specifies the standard for interactive multimedia compact discs designed for CD-i players. This format is unusual because it hides the initial tracks which contains the software and data files used by CD-i players by omitting the tracks from the disc's TOC (table of contents). This causes audio CD players to skip the CD-i data tracks. This is different from the CD-i Ready format, which puts CD-i software and data into the pregap of track 1.

Enhanced CD, also known as CD Extra and CD Plus, is a certification mark of the Recording Industry Association of America for various technologies that combine audio and computer data for use in both compact disc and CD-ROM players. The primary data formats for Enhanced Compact Disc's are mixed mode (Yellow Book/Red Book), CD-i, hidden track, and multisession (Blue Book).

Recordable compact discs, CD-Rs, are injection molded with a "blank" data spiral. A photosensitive dye is then applied, after which the discs are metalized and lacquer-coated. The write laser of the CD recorder changes the color of the dye to allow the read laser of a standard CD player to see the data, just as it would with a standard stamped disc. The resulting discs can be read by most CD-ROM drives and played in most audio CD players. CD-R recordings are designed to be permanent. Over time the dye's physical characteristics may change, however, causing read errors and data loss until the reading device cannot recover with error correction methods. The design life is from 20 to 100 years, depending on the quality of the discs, the quality of the writing drive, and storage conditions. However, testing has demonstrated such degradation of some discs in as little as 18 months under normal storage conditions.

CD-RW is a re-recordable medium that uses a metallic alloy instead of a dye. The write laser in this case is used to heat and alter the properties (amorphous vs. crystalline) of the alloy, and hence change its reflectivity. A CD-RW does not have as great a difference in reflectivity as a pressed CD or a CD-R, and so many earlier CD audio players cannot read CD-RW discs, although most later CD audio players and stand-alone DVD players can. CD-RWs follow the Orange Book standard.

The Red Book audio specification, except for a simple 'anti-copy' bit in the subcode, does not include any serious copy protection mechanism. Starting in early 2002, attempts were made by record companies to market "copy-protected" non-standard compact discs, which cannot be ripped, or copied, to hard drives or easily converted to MP3s. One major drawback to these copy-protected discs is that most will not play on either computer CD-ROM drives, or some standalone CD players that use CD-ROM mechanisms. Philips has stated that such discs are not permitted to bear the trademarked Compact Disc Digital Audio logo because they violate the Red Book specifications. Numerous copy-protection systems have been countered by readily available, often free, software.

By Jeff Field - In nearly every screenshot of someone's Linux desktop I see, there is inevitably a copy of XMMS running with a playlist of MP3s. Clearly, it would seem, using Linux and listening to MP3s go hand in hand. However, what can a Linux user who likes to listen to MP3s do on the road? Most of the flash-media MP3 players, such as the Rio 600, have no support under Linux, or flakey support at best. This is where the Mambo-X comes in.

The unit On the surface, the Mambo-X looks like any other portable CD player. However, combined with a CD-RW drive, the Mambo-X suddenly does not seem so plain. You see, the Mambo-X not only reads standard CDs, but will read CD-RWs and CD-Rs that are full of MP3s. On one CD, for instance, I fit 183 songs, about 10 times as many as would be on a normal CD. This is great when you are on the road or on the run and do not want to carry a lot of CDs with you. Put this player in your pocket with one CD and you have roughly eight hours of music at 192 Kbps, or more music as you drop the bit rate further. The unit gets about eight hours of battery life from a pair of AA batteries, and supports the recharging of either Ni-Cd, Ni-MH or Li-ON rechargeable batteries. On rechargable batteries, the unit gets about six hours of life. Included in the box was a set of earbud headphones, an AC adapter, the romote, the documentation, and the unit itself. The unit has fairly standard controls on it. On the face of the unit, there are buttons to enable skip protection (which is always on in MP3 mode and can be turned off in CD mode), skip tracks, play, stop and access the functions menu. In the functions menu, you can control play mode (random, repeat), bass and treble controls, and the hold feature, which disables the buttons on the player so that when it is in your pocket or in a bag the buttons do not get bumped and interupt play. The remote With the incredible amount of tracks you can fit on one MP3-CD, normal CD player controls just will not do -- skipping manually through as many as 200 tracks is just no fun. The people who make the Mambo-X clearly saw this problem, and included a small infra-red remote with bass and trebel controls, random, repeat, play, stop, mute and volume controls, as well as a number pad you can use to go directly to a song, instead of hitting forward 153 times. The remote is not thin enough to fit in a wallet, but will easily fit in a pocket. The remote is especially useful if you use the Mambo-X to play CDs through the tape player in your car (via a tape adapter and car power adapter, both of which can be purchased at most electionics stores). Limitations While this player seems to be very well rounded, there are a couple of issues you should know about that the manual covers, but are not always mentioned at places the unit is sold. The unit supports a maximum bitrate of 192Kbps, which is fine since most MP3s are 128Kbps (near-CD quality) and few are more than 192Kbps (as a matter of coincedence, 192Kbps is what I rip all of my MP3s at, fortunately). Another limitation is that the Mambo-X does not support multisession CDs, so if you want to burn a full CD of music you had better do it on the first try and close the CD when finished, or you can expect the Mambo-X not to read the disc properly. Neither of these are particularly hard limitations to deal with. One limitation that is a bit frustrating is that the Mambo-X does not display song titles as other players do, simply track numbers, which on a CD full of MP3 files is pretty useless. I hope that in future versions of the product this is reconsidered. Shock protection Like most other portable CD players on the market today, the Mambo-X has a buffer where it stores audio in case the unit is shaken or hit, causing a skip. For both MP3s and CDs, this shock protection stores 45 seconds worth of music. This really matters when walking or jogging with the unit on, as those activities really shake the unit consistently. Using the Mambo-X under these conditions, I could not produce a skip, which was very impressive compared to my old Sony Discman with 10 seconds of shock protection. Sound quality Using my Sony MDR-CD60 headphones, which while not quite studio quality, are good enough for me, I was very happy with the playback quality of the Mambo-X. I am not quite an audiophile, but I did not notice much of a difference between playing the CD and playing the MP3 from the Mambo-X. When played on a higher end stereo, the difference is noticable, but for portable playing, the MP3 sounds, for all intents and purposes, the same. Documentation The documentation included with the unit is well written and easy to read, and was a bit of a shock because I am used to CD players coming with the bare essentials. The manual for this unit goes through how to burn a CD for use with it, as well as useful information such as how the Mambo-X sorts songs that are in subfolders (it reads a folder and the songs inside, then the songs in the first subfolder, and so on). It tell you how to use rechargable batteries as well as the various functions. One interesting flaw in the documentation was that while it told me how to seek through a track, I could not get it to work. Nothing major, just something of note. Conclusion Because the Mambo-X uses the standard ISO-9660 format for CDs, any operating system that has software capable of burning a standard CD is compatible with the Mambo-X, and this may be its best feature. Whether you are using Linux on x86, on Alpha, a Macintosh, a Windows machine, or even BeOS, you can use the Mambo-X. This has great appeal, as most of the flash-media MP3 players are not compatible with Linux, or do not have the greatest support. The Mambo-X however, has full support, as all you need is to be able to burn a CD, something Linux does rather well. All in all, I am very satisfied with the features and playback of the Mambo-X. If you are in the market for an MP3 player, make sure you look at all the features the players have first. The Mambo-X is an OK solution, as it costs less than a lot of the other MP3 players and you need not worry about compatibility, so long as you have a CD-RW or CD-R drive. However, it is far from perfect, with the lack of song titles on the LCD and the limitation on bitrates. However, if you can live with these limitations, the Mambo-X is certainly a decent enough player. NewsForge editors read and respond to comments posted on our discussion page.

I had an audio CD that I burned with the latest version of Nero ( us. A). It played fine in my car CD player, but on some of the CD players in my house, the TOC fails to read. I thought it was the media, but I tried burning the same Nero Project audio CD using the same media using my Plextor drive, and it plays fine in all CD players. I even tried burning it on my laptop computer's CD burner and that also burns fine in all players. (I burned multiple copies on all three drives, so I'm certain it wasn't an issue with bad media.) It may be that the drive is too new and is not fully supported in Nero, but it could also be a firmware problem. I'm not sure what is getting written differently in the lead-in / lead-out that is causing the TOC to not read in certain CD players.

London, Oct 15 (ANI). Using cheap lenses like those used in CD players, scientists have devised a new way to collide individual photons and atoms, which may revolutionise quantum networks, making them cheaper and easier to build. Collision of single atom with a single photon is vital for operating many prototype quantum communications methods, including quantum networks and sending data using spooky action at a distance. The new technique uses cheap lenses to transfer data between light and matter. And, according to physicists from Singapore and Germany, the new method that Quantum communications offers theoretically unbreakable security by encoding data into the quantum characteristics of photons. Though the current method is successful, the cavities are only made in a handful of specially equipped labs around the world Its just really difficult to manufacture them, New Scientist quoted Christian Kurtsiefer at the National University of Singapore, as saying. Also, the high price of production limits the development of quantum networking technology. Now, Kurtsiefer and colleagues have discovered a much simpler method to encourage light and matter to interact in a vacuum chamber they corral individual atoms of the metal rubidium into an area no wider than a few 10s of nanometres, using optical tweezers. This small trap is fixed between two aspheric lenses similar to those used in CD players. With the help of the lenses, physicists could focus a beam of information-rich photons down to a spot immediately above the rubidium atoms holding pen. Under this arrangement the atom collides with around 10percent of the photons. Such a high collision rate was attained as the researchers chose the wavelength of the data-carrying photons to suit the metal atom. Kurtsiefer said that with better quality lenses, the 10 percent figure could be raised to 100 percent, and might also offer a low cost alternative to the expensive cavities currently in use. (ANI)

The compact disc player has become one of the most ubiquitous pieces of consumer electronics equipment in use today. Tens of millions of players have been sold to date. However, as pervasive as the compact disc player's presence is, the beauty and complexity of its design and operation are under-appreciated by most users. This brief text attempts to inform the reader of the basic fundamentals of the compact disc player. It is a assumed that the reader has a basic knowledge of the fundamentals of signal processing, although it is certainly not a prerequisite for learning a great deal from the reading.

As staggering as the release of the compact disc player was in 1982, the technology and theories which allowed it to be born were long in development. In 1841, the great mathematician Augustin-Louis Cauchy first proposes the sampling theorem. Nearly 80 years later J. R. Carson publishes a mathematical analysis of time sampling in communications. In a 1928 lecture at the American Institute of Electrical Engineers Harry Nyquist provides proof of the sampling theorem in "Certain Topics in Telegraph Transmission Theory". In 1937, A. Reeves proposes pulse code wave modulation (PCM). In 1948, John Bardeen, William Shockley, and Walter Brattain invent the bipolar junction transistor at Bell Labscompact digital circuitry is a reality. Two years later, in 1950 Richard W. Hamming publishes significant work on error correction and detection codes. In 1958 C. H. Townes and A. L. Shawlow invent the laser. In 1960 R. C. Bose publishes binary group error correction codes. That same year I. S. Reed and G. Solomon publish error correction codes to be used in the CD player 22 years later. Also early computer music experiments take place at Bell Labs. Fifteen years before consumers see the first player, NHK Technical Research Institute publicly demonstrates a PCM digital audio recorder with a 30 kHz sampling rate and 12-bit resolution. Two years later, Sony Corporation demonstrates a PCM digital audio recorder with a 47.25 kHz sampling rate and 13-bit resolution. A hemisphere away, Dutch physicist Klaas Compaan uses a glass disc to store black and white holographic images using frequency modulation at Philips Laboratories. Four years later, in 1973 Philips engineers begin to contemplate an audio application for their "video" disc system. A prototype disc with a 44 kHz sampling rate is run through a 14-bit digital-to-analog converter and exhibits a signal-to-noise (S/N) ratio of 80 dB in monaural. Now a research frontier, Mitsubishi, Sony, and Hitachi all demonstrate digital audio discs at the Tokyo Audio Fair in 1977. One year later, Philips joins with its recording subsidiary Polygram Records to develop a worldwide digital audio standard. In March 1979, Philips demonstrates a prototype compact disc player in Europe. Sony joins the Philips/Polygram coalition after Matsushita declines. In June of 1980, the coalition formally proposes their CD standard. A year later in 1981, Sharp successfully mass produces the semiconductor laser. This step was crucial to delivering a consumer product. In Fall of 1982 nearly 150 years of work comes to fruition and Sony and Philips introduce their respective players to consumer in Europe. The following spring, the player is introduced in the United States. Twelve years later, the improvement of digital audio continues at a rapid pace and the analog format that was so prevalent in 1982 has all but disappeared.

We can then easily compute for a sampling rate of 44.1 kHz, a signal of 23 kHz will be aliased to 21.1 kHz. More precisely, the frequency will be folded back across half the sampling frequency by the amount it exceed half the sampling frequencyin this case by 950 Hz. Hence the use of a brickwall filterone with a sharp cutoff characteristicon the input signal is necessary. The need for placing a filter after the DAC in the player may not be intuitively obvious. Imagine the limiting case of a sine wave at half the sampling frequency. There will be two samples generated for this wave, however the DAC will represent this as a square wave of the same frequency. From the Fourier series expansion, we know that a square wave consists of infinite harmonics. The DAC has now created frequencies that did not previously exists. Because the input signal was bandlimited, we know that it is reasonable to pass the output signal through another low-pass filter with the same characteristic as that used in the sampling process. This low-pass filter strips the higher-order harmonics from the square wave and we are left with the sine wave we started with. Due to its actions, this low-pass filter is often referred to as an anti-aliasing filter in the frequency domain and as a reconstruction filter in the time domain. A linear phase low-pass filter is characterized by having a symmetrical impulse response. In particular, the impulse response of a low-pass filter is the sin(x)/x function. When the reconstruction filter is excited by an amplitude varying impulse train from the DAC, the output is a linear combination of the individual amplitude modulated impulse responses.

Although rarely observed in a well designed player, jitter is a worthy topic of discussion because of both its misconceptions and the large amount of press it has received. Jitter is basically defined as time instability. It occurs in both analog-to-digital and digital-to-analog conversion. The latter instance is the only concern here. Jitter occurs in the compact disc player when samples are being read off the disc. These reads are controlled by the pulses of a crystal oscillator. If the system clock pulse inaccurately (an unlikely event), if there is a glitch in the digital hardware, or if there is noise on a signal control line, the actual reading time will vary from sample to sample thus inducing noise and distortion in the extreme case. A great deal of money has been made by shrewd marketeers preying on the fears of the consumer worried about jitter. Such products marketed include disc stabilizer rings to reduce rotational variations, highly damped rubber feet for the players, and other snake oil remedies. However, the careful engineer has beaten the marketeer to the punch by having the samples read off the disc into a RAM buffer. As the buffer becomes full, a local crystal oscillator can then "clock-out" the samples in a reliable manner, independent of the transport and reading mechanisms. This process is referred to as timebase correction and as stated before, any quality piece of equipment will implement it.

The compact disc player as a sound reproduction device fulfills the loop begun in the recording studio, returning the audio signal back to its original analog form. If all the theoretical guidelines have been followed in the equipment and processes between the musician and your audio system, the sound you hear is exactly the sound that was heard in the recording studio. The specifications for the compact disc and compact disc players were jointly developed by Sony, Philips, and Polygram as mentioned previously. This specification is contained in their standards document referred to as the Red Book. A summary of this standard is seen in Table 1.

The compact disc player contains two main subsystems. the audio data processing system and the servo/control system. The servo, control, and display system orchestrate the mechanical operation of the player and include such items as the spindle motor, auto-tracking, lens focus, and the user interface. The audio data processing section covers all other player processes. A block diagram of the compact disc player is shown in Figure 1.

Since the introduction of the compact disc player in 1982, the market has seen three generations of players. First generation players were characterized by multi-bit DAC's used with brickwall reconstruction filters. Second generation players used the same multi-bit DAC's but took advantage of digital oversampling filters placed upstream of the DAC along with a gentle analog reconstruction filter. Finally, current players make use of low-bit DAC's along with oversampling filters and the gentle analog output filter. In the following sections, each of these DAC types and filtering methods will be investigated.

The very first demonstration players made by Sony, Philips, and others used 14-bit converters, which at the time were a vast improvement over analog equipment, but nonetheless were poor quality by today's standards. By the time the first consumer players were released in 1982, 16-bit converters were the standard. By 1989, many manufacturers touted the use of 18 and 20-bit converters.

Because there are only two voltage references in the PDM converter, there is no level matching requirement for improved accuracy. Therefore the linearity errors associated with it are eliminated. Comparisons of THD and linearity error for various 16-, 18-, 20-, and 1-bit converters yield interesting results. PWM and PDM converters show 1 dB linearity for input signals from -100 to -80 dB and are virtually linear thereafter. Some of the most expensive players on the market with 18- and 20-bit converters using 4-, 8-, 16-, and even 32-times oversampling yield up to 4 dB linearity error for signals as high as -75 dB. In the THD tests performed with a -60 dB 1 kHz sine wave test signal, the expensive multi-bit players showed harmonics up to the 13th at levels greater that -110 dB

The compact disc has only existed for about 13 years, and more than likely has as many years of useful life left. There are many advances that are still possible in the format and many of them are just in their infancy. However, many challengers have already entered the playing field. some by the original creators of the compact disc. Sony has created both the DAT standard as well as the Mini-Disc, and Philips has created the DCC (digital compact cassette). Regardless of the compact disc's lifetime, it is certain that digital audio will remain, and analog will be reserved to the role of input at the microphone in the studio and output at the speaker in the listening environment. This is by no means a complete or exhaustive analysis of the basic fundamentals of the compact disc player. Many issues such as error-correction, data encoding and decoding, and pickup design were neglected. However, the concepts covered here should provide the reader with a strong background, and incite some interest in learning more. For the reader who is interested in learning more, the The Art of Digital Audio by Watkinson is an extensive collection of knowledge on digital audio. It is at times very technical in nature, but the material introduced builds upon itself nicely. Pohlmann's book, The Compact Disc Handbook, focuses solely on the compact disc player and the compact disc itself along with all its diverse formatsof which audio is only one. His book is very thorough in its coverage and should leave no questions from the reader unanswered. Pohlmann's book has a fair amount of overlap with Watkinson's and would make a better starting point for those short on time.

Reviewers rave about the sharp sound quality of the Sony D-NF430. This portable CD player comes with all the bells and whistles, including an FM/AM tuner, a weather band and audio TV stations. It can also play both

Regular CDs and MP3 files burned to CD-R/RW discs. A three-line display lets you view title and track information. This Sony player comes with a long battery life (about 41 hours), "G-Protection" to prevent skipping and a user-friendly remote. The downside is that it costs twice as much as other CD players -- and about as much as a small-capacity MP3 player.

Portable CD player uses two AA batteries, and an AC adapter is included. The Coby doesn't have a radio tuner, but most owners say it's good for simple CD playback.

Advantages. crisp sound, sleek design. Disadvantages. Time consuming to load lookup cd's. My 5 disc cd player had finally been laid to rest after a 10 year life. I decided if I was going to replace it, I might as well get a combo cd/dvd player, After a bit more research, I realized I could get a massive storage player for a bit more. So I bought a 200 disc cd/dvd player. Soon after hooking it up I found out it didnt play cdr or cdrw. Well, thats about 10% of my collection I wasnt willing to sacrifice. So, back to the store I went, and..Ive read some say the sound quality is subpar. I couldnt agree less! Ive found this player to have a sharp, crisp sound. I may not be an audiophile, but I am a music fanatic. This player is as clear as any I have heard. The layout of the machine is average. It is sleek, and not as large as I would have anticipated. The display is a blue color that is easily seen at night. The controls on the machine are also well layed out. There is a problem though..

Advantages. Very good Disadvantages. expensive Yamaha got it right with the CDC-697. It matched the track change speed of my 17 year old changer. If you regularly listen to music in random/shuffle mode, this CD changer is the only one out there (in 2008) that can change tracks on different disks within a reasonable time (8-10 seconds vs 15-20 seconds). Nothing else I tried out there that could do that. Yamaha also seems to have the best version of the disk exchange feature. All the players I..is still playing but the Yamaha is the only one that lets you change 4 of the 5 disks (the fifth is still playing). The others only let you access 2 of the 5 disks to change. I think Yamaha put more thought into the changer aspect of this model. One other benefit is that the CDC-697 is one of the few CD changers that supports CD text. I hope this helps others. Listen to hours of uninterrupted tunes with the CDC-697 from Yamaha. Its multi-disc.

Advantages. ok Disadvantages. no Mine has worked fine for over a year. Sound quality is not great through the analog outputs. Sounds good hooked up using the digital output to a receiver with an optical digital input. There's no excuse for a CD player in this price-range to sound bad (and it does) through the analog outputs ..It is really fun to Play tunes on Sony's CDP-CE375 Compact Disc Player it gives a nice and beautiful features. This 5-Disc changer has different features like.

First prototype CD player 'Goronta'[2] by Sony at the Japaneese Audio Fair in 1982, Sony showcased the vertical loading design of the CD player. Although the prototype's design was never really put into actual production, it was for a time adopted for production by a number of early Japanese CD player manufacturers including Alpine/Luxman, Matsushita under the Technics brand, Kenwood and Toshiba/Aurex. For the early vertical loading players, Alpine sourced their AD-7100 player designs for Luxman[3], Kenwood and Toshiba (using their Aurex brand). Kenwood added their 'Sigma Drive' outputs to this design as a modification. A picture of this early design can be seen on the Panasonic website.[4]

The laser pick-up of all CD Walkman models consumes less power and that extends CD Walkman player battery life to new record levels. The high-end D-EJ815 CD Walkman model has a battery life of up to 76 hours, while the entry-level D-EJ611 CD Walkman model has a battery life of up to 32 hours (twice as long as predecessor models).

Use of aggressive brickwall filters was required, which had sharp cutoff characteristics and linearity problems. Of course, it's. a pain in the rear to design a properly working brickwall filtering circuit. Enter newer CD players with oversampling, which pushes the aliasing well above the audible range. This means that an easier bessel filter, typically 2nd order, can be used to roll off the non-audible upper ranges added by oversampling to eliminate the aliasing noise from the outputs and to keep the amplification equipment from going non-linear.

Do anyone still use their CD Players? I know iPods and mp3's have taken the world by storm by the convenience of having many songs in a device that fits in your pockets. But do you guys have a CD player around that collects dust or use it once your iPod batterys dead? Or maybe you stick with CD players until the end? Well currently since my ipod needs charging, My CD player is just sitting around, so I might throw some batteries in it and play it since I still have CD cases around.

I still use my cd player all the time. I am waiting till the cost of an mp3 player goes way down. I am going to buy myself an mp3 player soon because it is more portable than a cd player. I don't always like what the radio is playing so this would be nice to have. I would still use my cd player at home though.

Well my cds stay at home in my car because i use my cd player in my car. i don't have a cd player at home because i can use my laptop. i do have an iPod i use for like running and stuff. I would like an iHome because it is convienent having all my music on one thing is nice.

I don't use my cd player much or at all and i also don't have a ipod or mp3 player. Every cd i get i burn to the computer and listen to it there. my car has a tape no cd, so i listen to the radio.

Don't ever use my cd player anymore.I don't even know where it is. I love my iPod, plus you can hold a lot more songs on a mp3 player then a cd = ]

I have a Cd player in my closet. It get use sometime. But nowaday I use my fabulous mp3 player that I got on my birthday. It can play movies, so that helps on long road trips.

I'm still old school. I have a yellow Sony CD player, and trust me.on those long trips to my grandparents' house, I use it. On these trips, I ride with my parents because it saves me gas money. In my car, I usually listen to my cds or my iPod. I hate the radio. The songs are way too overplayed.

Not really I have a cd player but its just there. i might end up selling it in a garage sale or something. I use an ipod now, i find it way better and much more varieties of songs, and easy to carry around. plus perfect when working out.

In June of 1980, the coalition formally proposes their CD standard. A year later in 1981, Sharp successfully mass produces the semiconductor laser. This step was crucial to delivering a consumer product. In Fall of 1982 nearly 150 years of work comes to fruition and Sony and Philips introduce their respective players to consumer in Europe. The following spring, the player is introduced in the United States. Twelve years later, the improvement of digital audio continues at a rapid pace and the analog format that was so prevalent in 1982 has all but disappeared.

We can then easily compute for a sampling rate of 44.1 kHz, a signal of 23 kHz will be aliased to 21.1 kHz. More precisely, the frequency will be folded back across half the sampling frequency by the amount it exceed half the sampling frequencyin this case by 950 Hz. Hence the use of a brickwall filterone with a sharp cutoff characteristicon the input signal is necessary. The need for placing a filter after the DAC in the player may not be intuitively obvious. Imagine the limiting case of a sine wave at half the sampling frequency. There will be two samples generated for this wave, however the DAC will represent this as a square wave of the same frequency. From the Fourier series expansion, we know that a square wave consists of infinite harmonics. The DAC has now created frequencies that did not previously exists. Because the input signal was bandlimited, we know that it is reasonable to pass the output signal through another low-pass filter with the same characteristic as that used in the sampling process. This low-pass filter strips the higher-order harmonics from the square wave and we are left with the sine wave we started with. Due to its actions, this low-pass filter is often referred to as an anti-aliasing filter in the frequency domain and as a reconstruction filter in the time domain. A linear phase low-pass filter is characterized by having a symmetrical impulse response. In particular, the impulse response of a low-pass filter is the sin(x)/x function. When the reconstruction filter is excited by an amplitude varying impulse train from the DAC, the output is a linear combination of the individual amplitude modulated impulse responses.

Although rarely observed in a well designed player, jitter is a worthy topic of discussion because of both its misconceptions and the large amount of press it has received. Jitter is basically defined as time instability. It occurs in both analog-to-digital and digital-to-analog conversion. The latter instance is the only concern here. Jitter occurs in the compact disc player when samples are being read off the disc. These reads are controlled by the pulses of a crystal oscillator. If the system clock pulse inaccurately (an unlikely event), if there is a glitch in the digital hardware, or if there is noise on a signal control line, the actual reading time will vary from sample to sample thus inducing noise and distortion in the extreme case. A great deal of money has been made by shrewd marketeers preying on the fears of the consumer worried about jitter. Such products marketed include disc stabilizer rings to reduce rotational variations, highly damped rubber feet for the players, and other snake oil remedies. However, the careful engineer has beaten the marketeer to the punch by having the samples read off the disc into a RAM buffer. As the buffer becomes full, a local crystal oscillator can then "clock-out" the samples in a reliable manner, independent of the transport and reading mechanisms. This process is referred to as timebase correction and as stated before, any quality piece of equipment will implement it.

The compact disc player as a sound reproduction device fulfills the loop begun in the recording studio, returning the audio signal back to its original analog form. If all the theoretical guidelines have been followed in the equipment and processes between the musician and your audio system, the sound you hear is exactly the sound that was heard in the recording studio. The specifications for the compact disc and compact disc players were jointly developed by Sony, Philips, and Polygram as mentioned previously. This specification is contained in their standards document referred to as the Red Book. A summary of this standard is seen in Table 1.

The compact disc player contains two main subsystems. the audio data processing system and the servo/control system. The servo, control, and display system orchestrate the mechanical operation of the player and include such items as the spindle motor, auto-tracking, lens focus, and the user interface. The audio data processing section covers all other player processes. A block diagram of the compact disc player is shown in Figure 1.

Since the introduction of the compact disc player in 1982, the market has seen three generations of players. First generation players were characterized by multi-bit DAC's used with brickwall reconstruction filters. Second generation players used the same multi-bit DAC's but took advantage of digital oversampling filters placed upstream of the DAC along with a gentle analog reconstruction filter. Finally, current players make use of low-bit DAC's along with oversampling filters and the gentle analog output filter. In the following sections, each of these DAC types and filtering methods will be investigated.

The very first demonstration players made by Sony, Philips, and others used 14-bit converters, which at the time were a vast improvement over analog equipment, but nonetheless were poor quality by today's standards. By the time the first consumer players were released in 1982, 16-bit converters were the standard. By 1989, many manufacturers touted the use of 18 and 20-bit converters.

Because there are only two voltage references in the PDM converter, there is no level matching requirement for improved accuracy. Therefore the linearity errors associated with it are eliminated. Comparisons of THD and linearity error for various 16-, 18-, 20-, and 1-bit converters yield interesting results. PWM and PDM converters show 1 dB linearity for input signals from -100 to -80 dB and are virtually linear thereafter. Some of the most expensive players on the market with 18- and 20-bit converters using 4-, 8-, 16-, and even 32-times oversampling yield up to 4 dB linearity error for signals as high as -75 dB. In the THD tests performed with a -60 dB 1 kHz sine wave test signal, the expensive multi-bit players showed harmonics up to the 13th at levels greater that -110 dB

The compact disc has only existed for about 13 years, and more than likely has as many years of useful life left. There are many advances that are still possible in the format and many of them are just in their infancy. However, many challengers have already entered the playing field. some by the original creators of the compact disc. Sony has created both the DAT standard as well as the Mini-Disc, and Philips has created the DCC (digital compact cassette). Regardless of the compact disc's lifetime, it is certain that digital audio will remain, and analog will be reserved to the role of input at the microphone in the studio and output at the speaker in the listening environment. This is by no means a complete or exhaustive analysis of the basic fundamentals of the compact disc player. Many issues such as error-correction, data encoding and decoding, and pickup design were neglected. However, the concepts covered here should provide the reader with a strong background, and incite some interest in learning more. For the reader who is interested in learning more, the The Art of Digital Audio by Watkinson is an extensive collection of knowledge on digital audio. It is at times very technical in nature, but the material introduced builds upon itself nicely. Pohlmann's book, The Compact Disc Handbook, focuses solely on the compact disc player and the compact disc itself along with all its diverse formatsof which audio is only one. His book is very thorough in its coverage and should leave no questions from the reader unanswered. Pohlmann's book has a fair amount of overlap with Watkinson's and would make a better starting point for those short on time.

The compact disc player has become one of the most ubiquitous pieces of consumer electronics equipment in use today. Tens of millions of players have been sold to date. However, as pervasive as the compact disc player's presence is, the beauty and complexity of its design and operation are under-appreciated by most users. This brief text attempts to inform the reader of the basic fundamentals of the compact disc player. It is a assumed that the reader has a basic knowledge of the fundamentals of signal processing, although it is certainly not a prerequisite for learning a great deal from the reading.

As staggering as the release of the compact disc player was in 1982, the technology and theories which allowed it to be born were long in development. In 1841, the great mathematician Augustin-Louis Cauchy first proposes the sampling theorem. Nearly 80 years later J. R. Carson publishes a mathematical analysis of time sampling in communications. In a 1928 lecture at the American Institute of Electrical Engineers Harry Nyquist provides proof of the sampling theorem in "Certain Topics in Telegraph Transmission Theory". In 1937, A. Reeves proposes pulse code wave modulation (PCM). In 1948, John Bardeen, William Shockley, and Walter Brattain invent the bipolar junction transistor at Bell Labscompact digital circuitry is a reality. Two years later, in 1950 Richard W. Hamming publishes significant work on error correction and detection codes. In 1958 C. H. Townes and A. L. Shawlow invent the laser. In 1960 R. C. Bose publishes binary group error correction codes. That same year I. S. Reed and G. Solomon publish error correction codes to be used in the CD player 22 years later. Also early computer music experiments take place at Bell Labs. Fifteen years before consumers see the first player, NHK Technical Research Institute publicly demonstrates a PCM digital audio recorder with a 30 kHz sampling rate and 12-bit resolution. Two years later, Sony Corporation demonstrates a PCM digital audio recorder with a 47.25 kHz sampling rate and 13-bit resolution. A hemisphere away, Dutch physicist Klaas Compaan uses a glass disc to store black and white holographic images using frequency modulation at Philips Laboratories. Four years later, in 1973 Philips engineers begin to contemplate an audio application for their "video" disc system. A prototype disc with a 44 kHz sampling rate is run through a 14-bit digital-to-analog converter and exhibits a signal-to-noise (S/N) ratio of 80 dB in monaural. Now a research frontier, Mitsubishi, Sony, and Hitachi all demonstrate digital audio discs at the Tokyo Audio Fair in 1977. One year later, Philips joins with its recording subsidiary Polygram Records to develop a worldwide digital audio standard. In March 1979, Philips demonstrates a prototype compact disc player in Europe. Sony joins the Philips/Polygram coalition after Matsushita declines. In June of 1980, the coalition formally proposes their CD standard. A year later in 1981, Sharp successfully mass produces the semiconductor laser.

Digital sound in some ways is like your digital watch. Either it tells the right time or it doesn't. When companies that make expensive CD players insist that their devices inherently sound better, use your ears and judge for yourself.

Despite manufacturers' claims, compact disc players sound pretty much the same to most listeners. The minor differences that are sometimes heard may be real or they may be imagined. It's not possible to determine the issue closer than that, at least with any certainty. I have discussed this issue before in considerable detail, and I am mentioning it now because a number of readers have asked about the sound of CD players. The typical question is, Do more expensive CD players sound better? The answer is no. Why, then, do some compact disc players cost so much more than others? Is it a rip-off? Not really. The decision to price some CD players high is a marketing move. Companies know that most consumers equate price with quality, and in hi-fi gear, quality is supposed to be synonymous with better sound. Oddly, more expensive CD players may not bring in extra profits. They will surely cost more to make, and unless they sell in large quantities, they may not even pay for themselves. Cheap players, which may sell by the hundreds of thousands a month, nearly always make more money for their manufacturers than more expensive players do. So why take a chance on losing money with expensive compact disc players? It's simple. Money, as Yuppies already know, is only part of the game. Technological dazzle, exclusive design touches and recommendations of those already in the in group are all very important, and they mean the same to the makers of hi-fi components as they do in the auto business. Just as BMWs, which are svelte and expensive, help sell Nissans to those who want the svelte but don't have the pelt, so the $1,000 CD players help sell the $300 models to those who can't yet afford the top-of-the-line. The psychology works well. And that is generally all there is to it -- except for those few hi-fi buffs who insist that they can hear the difference between a cheap player and an expensive one. Maybe they can, and maybe they just think they can. Objective tests nearly always find such claims to be baseless. But there is one area that is not so sharply shaded. Of all the esoteric (and expensive) CD players, one model tackles the problem of reproducing sound in a unique way, and the principles it employs are so far out of the mainstream that they may be either completely wrong or totally right. That player is the Kinergetics KCD-20, a limited-production model that includes special circuitry that is designed to cancel distortions that the company says are inherent in all electronic devices. Backing up Kinergetics' claim is its impeccable background. It is the developer of a successful circuit that removes distortion from the amplified speech of deep-sea divers. Further, it has used its research in this area to develop devices that do, in fact, cancel out problem sounds in such components as tape recorders. The KCD-20 compact disc player, at $800, is about four times the cost of a typical bottom-line CD player from one of the major manufacturers. Does it sound four times as good? No, not at all. In fact, my first listening sessions found no difference at all between the Kinergetics player and two or three others I had on hand. But extensive listening has brought doubts that my first judgment was correct. Over the period of four or five months, the KCD-20 has come to sound more . . . well, more gracious, if that is the way I should describe it. I find that I prefer its sound to any others, but I am not sure why. Perhaps I have been snared in a psychological trap of my own making. Maybe I just want that player to sound better. Maybe it really does. At some point in our technological education, we may begin to solve minor mysteries like this. But until then, we will have to be content with small reminders of how little we actually know about the mechanism of perception.

In-dash CD players have been a staple of car audio for nearly two decades now. But, with CD sales declining and digital music sales soaring, it seems the in-car CD player is going the way of the cassette deck (and the 8-track before it). German car audio manufacturer Blaupunkt -- popular with the 'Pimp My Ride' set -- has ditched the CD player in its new Melbourne SD27 head unit in favor of a slot for SD or MMC memory cards. The unit will play both MP3 and WMA songs directly from the SD card, displaying song information on a 30-character front-panel display, which, to be honest, we find a bit small by today's standards -- especially given the room freed up by the lack of a CD slot. It won't play AAC songs, so iTunes fans who don't want to convert their tracks will need to hook up their iPods through the line-in jack, which also works with any other media player, of course. The SD27 is also Bluetooth-compatible, so it can do hands-free calls and even stream music directly from other Bluetooth-compatible devices. The Melbourne SD27 goes for $159.95 -- a small price to pay for freeing your glove box up for what it was really meant for. napkins and ketchup packets. From GizmagRelated Links.

Bah. I'm not even ready for a CD player in my car yet. I can always listen to those at home. But what am I going to do with all my great old cassettes if I can't get a player in my next car? And who has time to learn a whole new technology just for downloading songs, & then spend all that time searching for & downloading them? Kids, maybe, but not a single Mom with 2 jobs.

Seems to me everything is going mobile digital, satellites are the endeavor of choice for all media and/ or relations. So those money grabbing radio services are going to have to pick up where typical radio channels are leaving. As for these custom music players go, I've got to feel there going smaller. Indeed, watch size, sun-glasses, two which are available. And that blue tooth, wow, can anyone think "stay at home library" for your media sorts, for everyone of course. Ok, my conclusion is that even though.We're "SELF-INDULGED", money is root.., some people dont like change (8-track to cassette, to cd, to mp3/wma, to some "opened-source" (remember smaller is better, so music/media files any larger is bad (gigabytes, terabytes, petabytes, exabytes-are all resource hungry), companies bring upon innovations for everyday people (people them-selves of course), robots are gaining a real A. I. for.., and space and time are becoming more defined in our language. We indeed are capitalizing on a bigger and better tomorrow (included are 3 hugs (lol)) hpoe to see ya ALL there. IN GOD WE TRUST...

When you got Sirius satelite radio, you don't need the cd player anyway! I never play cd's in my truck now, but rather just use my favorite artist stored in my satelite, and then ''fm'' frequency it over to my pioneer as it is. I initally thought, that my clarity would be less with my audio system (amp & subwoofers), but found it sounds just fine! With 198 channels, and the ability to rock out to just about anything under the sun at anytime and mood change, the Sirius is the way to go anyways for me! On a side note, cd players will hot for years to come! You might have the new stuff on digital media, but I betcha don't have that good old cd of the 80's, too hard to find online, in mp3 format!

I will always like having an actual, physical disc -- not just invisible digits -- to represent and encompass an album. And, I like having album-sized collections. ten or so songs at a time is plenty. Some of us, too, have vision or other physical problems that really make the typical new screens and buttons annoying to use. I like CDs, and listening to one in my car on my car player is one of the day's nicer things. It's easier to do than it is at home, where there are often many interruptions (.I don't like wearing portable headphones all around the house).I especially like CDs that have companion booklets with them, these days. Though, I won't read while I drive!

You would still be able to listen to CDs or cassettes with one of these players by connecting any portable player from it's headphone jack to the line in on the car amp, or by bluetoothing.

This doesn't surprise me. I no longer drive (I live in NY and haven't driven in almost 2 years), but even the last time I drove, I had barely used my CD player or normal radio in a couple years because of the great selection of XM radio stations playing all the current hits with a great variety of choices, and that I was able to hook my iPod into my car. Good-bye CD players.(

Im not going to change anything - I need a rest for it. Im tired keeping up with whats next out.Im stopping here. I play the cds.and portable tape player kept under my seat. Tthat's it. Done. Maybe in 20 years I may be interested in a newer concept. The End.

When is this BS going to stop? I don't own an MP3 player and have no intention of ever owning one. They are expensive and sound like garbage. I just bought a new car and have a cd player, which is ok. But now I have to transfer all my music from cassettes to cd. Now the technogeek yuppies are trying to force their new, low-quality technology down our throats. It's time to stop the nonsense!
