I hate to pick a quarrel on yet another subject, but I've never really understood this knock against CDs. The early generation did not measure up to LPs in sound quality, but by now they are quite satisfactory in that department as far as I am concerned, and their lack of surface noise and much greater dynamic range are clear points in their favor. But I guess it's basically a matter of personal preference. (BTW, I listen primarily to classical music and jazz -- but there are listeners in those categories who swear by the superiority of vinyl.)

Once you've turned a sine wave into a square wave, the best algorithm in the world isn't going to duplicate that sine wave.
al·go·rithm n. A step-by-step problem-solving procedure, especially an established, recursive computational procedure for solving a problem in a finite number of steps. (American Heritage Dictionary, 4th ed)
How many finite number of steps in a sine wave?
Maybe not an audible issue, but it *is* one to note.
It's interesting that you should be a jazz classical listener.
In my experience as a live sound technician I often noted(heh) that jazz players like transistor/IC amplifiers, and blues/rock musicians prefer tubes. It has to do with distortion.
When a transistor amp distorts, it feeds back even-order harmonics (1,2,4,8) which aren't very "musical", however, when a tube amp distorts, the harmonics are odd-order (1,3,5,7) just like a chord on a piano or guitar. Hence, a "warmer" sound to the audio, because there is *always* some level of distortion present in the reproduced waveform.
The same is true in "overdrive". Many transistor guitar amps have a tube stage to feed distorted sound to the transistor stages for that aspiring "Jimi" that can't afford the stacks of Marshalls, or the tubes (they ain't cheap in matched pairs).
