If you are talking bi-amping with respect to the B&W Diamond speakers my experience is it yields little to no audible difference for the simple fact that the speakers can not be actively bi-amped, it's a passive bi-amp. I horizontally bi-amped my 802 Diamonds with two 4B-SST amps and did the same with my 800 Diamonds. I had the two amps on hand so it didn't cost me anything to experiment but I would advise based on my experience not to spend the money on a 2nd amp if you don't already have one.

I was thinking at first to use them as mono but changed my mind and then thinking of biamping, thinking of buying a second one but I don't think I will do that also. Thank you very much Rod  for sharing your experience.
