I use Sonoran Plateau's http://www.audiopoints.com, two sets for bi-wiring. They're copper, but sound so good that I'm using them instead of the Kimber silver cables that came with my B&W Silver Signatures. The shielding is steel micro-beads and they can lay on the floor, on top of each other or where-ever and nothing affects them.
