New music, especially classical and jazz, continues to be released on CDs. Many of these are well recorded with great sound quality when played on the latest generation of CD players and CD transports (optical drive mechanism only providing digital output requiring external DAC).
The latest players have better servo mechanisms and electronics giving a better read off the disc. Some CD players are dedicated purist designs specifically tuned for 16bit/44.4kHz CDs only, while others have digital inputs for other digital sources.
The increasingly delivery of music via streaming services and digital file downloads has resulted in the departure of many optical drive manufacturers and prices have crept up. However sound quality is better than ever so those with rare CDs, or very large collections, can continue to enjoy their CDs.
CD Players typically last 7-10 years before the laser has dimmed with age to the point where error correction is no longer able to compensate for missing data and the player begins to mistrack or displays the dreaded 'no disc'. Installing a new mechanism is not always a straight forward option because it has to be compatible with the older controlling electronics. Sound quality will be limited by the older DAC. Purchasing a reliable new player with better sound quality and a full warranty is usually the best (or only) option.
Half-width and full-width products are available in both top-loading and front-loading slot or tray physical formats.
Cyrus audio and NuPrime audio CD Players can be upgraded with an external low-noise regulated power supply for maximum performance.
Primare's CD Players have an optional streaming module keeping all the digital in one box leaving the amplication completely analog and is a good combination
for those who have not yet explored subscription based streaming services with their wide selection of music.
CD transports are indicated if you already have a premium external DAC or integrated amp with a built-in DAC, or if regularly upgrading a stand-alone external DAC appeals.
As CD player prices have crept up, high-resolution digital file music libaries become more competitive. Once your CDs are ripped to a Music Library (juke box) you have more convenient access to your music collection and you can create playlists as well as opening the door to downloading and locally streaming higher resolution digital files. Playing music from a Music Library extends the life of your aging CD Player and reduces wear and tear on your CDs some of which may never make it over to a streaming services library. Many remain happy to continue to use CDs particularly if you already have a large collection.
Power conditioning, isolation platforms and better digital coax, optical or analog cables will all improve sound quality.
