if your serious about wanting good music...
http://stereophile.com/digitalprocessors/731/ would be the best you would ever spend your money on... 1600.00 is alittle pricey for a computer based sound system imo.
also here are some reviews on some wonderfull sound cards that have been considered worthy enough to be reviewed by Stereophiles:

prepare to spend 300+ for a good audio card but it's the best money you could ever spend imho... your software is only as good as the card it goes though, get good software and a good card and everyone will think your Paul Klipsch
i'm looking at the Razer and it seems like a very nice card, but i personally don't like the host of features, if your listening to music you want as few as features to keep from cluttering up your musical imaging, but then again i'm not too concerned with game audio
but decent enough specs although i would like to see some actual chip set numbers and tolerences.
