So, Randy, you're saying that the D/As on your average soundcard are probably not going to be even as good as a CD changer like I have in my HT. Because I CAN hear a clear difference between the using D/A's on my CD changer through analog in on my pre and using the D/A's on my receiver using digitial in. So, am I to assume that the D/As on even the best soundcards would not match my CD changer (approx. $300 USD changer)?

I hope I'm not milking this to death for you? I appreciate you replies, Randy! Thx! -Greg :-)
