Hi, I am currently running a pair of m3ti's with an older Denon avc-2800 receiver (if anyone knows where I can get a manual, plese let me know). I am looking for the best way to connect my computer to the receiver. Right now, I'm just using an Acoustic Research chord that goes from the 1/8th out on my SB Audigy 2 to the rca-in on the Denon. I guess my question is:

What kind of quality does a computer CD drive provide?
Will my current setup cause a significant loss of sound quality?

Any other suggestions would be greatly appreciated. Thanks!
