DH Labs makes the brand Silver Sonic - can't touch it for double the price. Speaker cable is called T-14, runs $4/ft and is a thick silver coating over copper with teflon insulation in a twister pair configuration. Interconnects are the BL series starting at $100 for 1m set. They also sell internal hookup wire, which is pure silver 20gg I believe for dirt cheap. check out their site at www.silversonic.com
