Xxxjo, any power cord that does not limit current will not degrade sound or cause damage to your equipment. There is no such thing as a fast or slow power cord, you could forget that part of your hunt I would say.
Hee: Not much diff. The Slvr is a bit better in the bass, IMO. These cords are good for the money but you may have to move up in price for the best performance. The AZ pc's are good but at $1500?
Hee: I think the Sigma is tighter in the bass (kick drum is impressive) than the SLVR. I don't think there is any volage drop with the Sigma since it uses 11-gauge silver wire. Some power cords can sound bloated in the bass too. You may want to try a few others to get the best match for your system.
