I remember around the mid 90s Hi-Fi choice began to claim that they
had managed to correlate the difference in CD players to measured
jitter, and all their reviews included jitter tests. It was pretty
convincing, though they never seemed to go on with it.

Every CD player ever made reclocks the audio that comes off the disc. The
book answer is that the only source of jitter is the word clock that drives
the DAC. In fact, there are primary and secondary paths by which disc
condition can trigger jitter in crappy players.

As a rule, one just doesn't see jitter at audible levels in good CD players.


Here's a serious question for you, Arnie, in line with Jenn's new
parameters for a well behaved NG.

To what degree do you believe tracking error or poor error-correction
in CD players contributes to sound quality? How important do you rate
efficient error-correction in the design of a CD player?

I have further questions along this line.
