So the answer is a most profoundly stated YES. :) *bzzt* Thank you for playing! Most modern soundcards (certainly the GUS and the SBPro) mix the audio out from the CD drive directly into the card output; it isn't "sampling" the sound and then replaying it. Now, it's perfectly true that the quality is a little lower than a "real" CD player, but the difference on my Panasonic CR-562B/GUS combination is almost inaudible; typically the only "difference" I can hear is removed by a little judicious use of the EQ on the stereo. I've also heard the same drive playing back through an SBPro, and it sounds just as good (in fact, it's a little better than the SBPro owner's (rather old) CD player!). Now, if you actually want to sample off the CD, that's another matter. The reason I often play audio CDs back thru the PC is so that I can take advantage of decent programming features; I've yet to see an affordable CD player which can remember programs for multiple CDs, recognise the CD, and replay the associated program. (Come to think of it, I don't think I've ever seen a CD player with this feature, regardless of price; I remember it was touted as a neato feature years ago when CDs were gaining popularity).
