I'm using the Anti-Cables bi-wired with an Ayre V1xe, and Vandersteen 5A's. There are 4 wires each side from the amp to the speakers. They are not twisted and as far from each other as possible. The sound is stunning.

I find myself intrigued the Speltz speaker-cable option, in part because the prices are like zero when compared to most speaker cables, but I wouldn't mind reading reactions beyond those he includes in his ads and on his web site.
