i've jumped in with both feet for playing cds stored on my hd on my xp box. i've added 2 gigs, another 500 gig hd, a pc power & cooling 500w ps and an audiotrak prodigy hd2 soundcard, and changed out its opamps. i listen to this stuff in my home 'office' exclusively thru headphones and a diy headphone amp that sounds really good. analog from the sound card to the headphone amp is shunyata antares i/c , btw. now the REAL fun can begin!! what tweaks have you guys found to work well inside the box, to make the sound better? ers cloth, carbon fibre wraps, shakti onlines/stones, marigo dots, ferrite clamps etc???? along with comments on how the sound improved -- i'm willing to get my hands dirty, but thought i'd see what others have found to work well for them. if all this pans out, i may try an assault on the cics style of dedicated machine and put it in the big rig.
