Okay - I consider myself pretty enthusiastic about my music and the quality of. I'm the type of guy to go through 5 receivers in a year and return countless sets of speakers. I'm picky.

I have the cheapest soundcard with a Radio Shack cable hooking into the CD input on my receiver. The sound is INCREDIBLE. I've literally compared it to the same song on CD, and can't hear even a smidgen of difference.
