Hi, I use for my Extreme, Purist Venustas WBT (BI-WIRING) and really work wonders with my Krell KSA-300S power, bony components baffles, and power cables should be treated like a unit, since according to how reconciles the end result will sound.
As I suggest most economical recommendation the Purist Aqueous 20 Anniversary, another cable with excellent cost-benefit ratio.
Greetings Adrian
