I'm not sure if you're inferring he wanted to sell more expensive wire or not...
However, the bi wiring subject came up innocently when the metal strap/bridge came out from the speakers connection and there was a noticeable change in the sound.
Any experience with bi wired MA's anyone?
BTW, I ordered all the interconnects and wiring, including the bi wires, from Signal Cable today.
not with your particular brand but no one that i know who's had biwiring performed in an unsighted manner has been able to tell whether their speakers were biwired or not. while it doesn't hurt it does lead to an additional expense. if you've got a couple of friends to help you out, i'll give you a link wherebye you can try it out for yourself and come to your own, independent conclusion.
