But you don't get 0s and 1s out of the replay chain, you get analogue waves. It is *possible*, I think, for a CD-R to have different jitter characteristics to an original, and jitter alters the analogue wave you get out. Assuming a difference is there (and I'm not saying it is: I don't know), I'd think you'd need pretty serious kit capable of *very* good resoltyion to notice it.
