I switched from the standard cable. I tried various cables, some co$$tly, others not so expensive and settled on the Kimber Palladian 10 (four of them, one for each monoblock). Yes, it is costly, but the difference is just short of incredibe. Dead silent, black backgrounds, perfect bass, clarity, speed, etc. In addition, I would recommend AC line conditioners. I use four Audio Prism ACFX, one for each of my four monoblocks, and they have cleaned all the grunge and noise. For low AC level equipment, such as preamps, etc., I use the Monster Signature 7000, which lets me lift the ground on the outlets and, htus, get much better sound. I was one of the many skeptics about power cables and conditioning, but since I tried them I can attest to their benefits (and I hate to admit it).
