best Bi Wire

Your question is too vague with way too many unanswered variables if you expect a worthwhile response.

My suggestion and of course YMMV:

I recently upgraded all my cables to Cabledyne silvers, best decision since my Siltech Gen. 5s. I am in no way a dealer or affiliated with this company. These cables are simply a good match for my system. The Bi-wire speaker cable is 2.0m in length with upgraded Furutech bananas, $890.

thanks for the suggestion. I'm not stuck on any one brand , just looking for people's expreiences with different bi wires. Where did you buy the Cable dynes?
