A good site for DIY'ers. I made some bass traps and panels on Jon Risch recipe. It made significant improvement in sound when i had them and my system in a small 10'x12' room. I had to let them go once i shifted my system in living room for WAF.
Hmm This article Jon_Risch's Web Site leads me to beleive that a PC will always remain inadequate (compared to high-end audiophile standards) source of music no matter what quality of sound card/DAC used, due to its power supply.
