I have the William Tell Silver Biwire speaker cables. I did not initially find them to live up to their advance billing, or their price, although they did improve substantially over a rather long break in period. However, at the strong recommendation of my dealer, who sympathized with my disappointment, I bought the new AQ Thunderbird ICs because he said the synergy of the two AQ wires would bring out the potential of the WTSBs. With just a couple weeks of the Tbirds in the system, the sound is considerably improved, making me think his reasoning was valid. This is not to imply that these wires wouldn't be good with other brands or equipment. I have no basis for commenting on that.
