Two 330A versus one 860A?

The 860A is head and shoulders better than the 330 monoblocks that's why it costs so much more it wouldn't even be a fair comparison I have used SIM audio for over 30 years now I have the w8 amplifier and p8 preamp, the evolution series is far superior to their lower line, if you can afford the 860A get it.

If all else is equal, the physical separation can reduce crosstalk and improve separation, but it appears that the 860A has some advantages over the 330, which will likely offset the benefit of two monoblocks.

Thanks everyone! Now have a much clearer idea how to proceed. Best,
