Pmboyd,
Sorry, I misread your post. From my research good silver speaker cables will present a lot of detail, but lack the warmth of copper. Since you're using hybrid ICs it may be worth trying the silver cables, but my Alpha Core/Goertz recommendation would not apply here as they are out of your budget. However, I would still recommend the copper Python Bi-wire and perhaps you can find a suitable silver cable to compare against. As I previously mentioned these are offered on a 30 day trial basis so not much to lose.
