I'm using my AVR300 with PMC DB1 speakers and although I'm very impressed with the sound, I'd like to try bi-amping the front speakers using the two extra surround amps as you can do with the AVR300. I'm currently using Linn speaker cable, carried over from my previous non-Arcam/non-PMC system. Can anyone recommend a cable for bi-amping that would suit the characteristics of the Arcam/PMC combo?
