Curious as to what others do:
I was considering bi-wiring my floorstanders. With the m700, I can use one set of outputs on the amp side to the four connectors on the speaker side. Or I could, use all four amp outputs to all four speaker inputs. For the 4-to-4 connection, I was thinking of using the Canare 4s11. This should still be a 14 gauge wire which should be more than enough considering the total distance from amp to speaker is about 6 feet.
For those that bi-wire, which do you prefer? What wire do you use?
