Forgot about one.
Get several of the "anti-static foam mats" for IC's from Radioshack. Cover the conductive foam so it does not short out your equipment. Place the mats over the IC's in the CD equipment, the D/A converter, the clock... etc. It will suck up the stray radiation and mellow out the sound.
