Re: And...who still plays CDs ? 5 disc changer Posted by Snowmobile [Email] (#686) [Profile/Gallery] (more from Snowmobile) on Tue, 8 Nov 2016 09:33:45 In Reply to: And...who still plays CDs ? 5 disc changer, GFW3pedals [Profile/Gallery] , Tue, 8 Nov 2016 07:23:22 Members do not see ads below this line. - Help Keep This Site Online - Signup |
Yup... people even still buy and sell CD players! See Audiogon (a used audio marketplace) for examples (up to $40000):

Companies still manufacture new ones, eg:
https://www.naimaudio.com/cd-players
There are CD players selling used for more than the cost of SAABs... LP's (turntables) even more so...
There is a reason for this. MP3's are compressed audio, and generally contain artifacts which one may or may not perceive depending on how bad the compression algo was (there are some very good ones), how much compression was used, how much one cares, if one knows what to listen for, etc etc... you can train yourself to hear them by compressing a compressed file repeatedly... with enough repetitions, the artifacts show up... like a tape copy of a tape copy getting noisier back in the old days!
People have gone for MP3s and other digital file based formats for convenience. There are lossless formats (eg FLAC) that are capable of better resolution than CDs. However, they take up more data (disk/bandwidth) so are not hugely popular... since what most people want is the convenience (more songs, vs better songs)...
Basically, well implemented CD is better than MP3s from a sound quality perpective so some people who care about sound still like them... that said, in many cases CD player implementations (or recordings on CD) are not necessarily great anyway... and the 5 disc changers were for the most part designed for convenience, not so much high fidelity... (and fwiw, CD's were produced as a convenience alternative to the LP - the audio fidelity is really no better on comparably good "audiophile" systems)
re noise shaping... what they are talking about is not analog noise in the electronics that you want to get rid of... a digital audio signal uses dither (for a number of reasons - one being to resolve low signal values properly), and by modifying the spectral shape of the dither (noise) appropriately, you can make it sound better. I'm simplifying significantly for brevity... The "multi level noise shaping" is still just advertising jargon, as there are lots of different ways to acceptably reproduce a signal and that's just some jargon for the way they did it (which is probably nothing spectacular).
