Hi,
I'm from Perth Australia.
I bought a high current silver Power cord from Joe of Custom Audio. He is genuine and the connectors which use top grade Furutech are excellent. The PC did not arrive on time as it was misplaced by the Post but Joe sent another PC. I ended up having two but sold off one to a friend at Joe's request.
He is ok and the service is excellent. The silver PC gives a much smoother presentation and wider soundstage. Silver in Power cords seems to have the opposite effect of silver in ICs and speaker cables. May be its because they are a much more efficient conductor.
Hope this helps.
regards
Yasont
