I drive a Duo 3.2 pair with the Yamamoto A-08 stereo amp (replaced Wavelength Venus). After trying a number of more expensive cables, including Nirvana SX (grossly overpriced, disappointing performance), I ended up with Grover Huffman's silver UR (8' speaker cables and 2' jumpers confiqured like the Cardas jumpers supplied by Avantgarde). The total cost for the speakers cables and jumpers was around $400. I also use his UR interconnects(around $175/1m pr).
