Biamping Questions

Hi All,

I want to biamp my JM/Focal speakers from four out of 7 channels of my Arcam unit. I know there are different ways to do this, but I was wondering if different kinds of speaker wire might be one way to go. For example, are there some speaker wires better for bass and midrange and other brands/types better for treble? Might that produce a good result?

I'd also appreciate any other advice you folks might be willing to give.

Thanks in advance,
russ
