Biamping B&W 802 with Musical Fidelity and Bryston

IMHO, biamping rarely solves any problem except for marginal power issues. Buy the amp that does the job and sounds right to you.

I agree. This is why the idea of second MF looked to me very appealing. It would double the power and I would not have problems with different gains and impedances. MF is actually dual mono amp. I would technically have 4 mono amps to do both vertical and horizontal bi-amping.

Biamping with identical amps does NOT double the power because the energy spectrum of music is not uniform. The power gain, if any, is marginal. A single amp with twice the power is more but, still, not more than a few dB.

It's a good point. I did not think about it.

There's nothing scary or hard about bi-amping, and the audible benefits are many. I've been actively bi-amping for years(tube top/SS bottom), but it's much easier with two identical amps.
