Amp Config for B&W 802D's

I see a lot of discussion of Brand A vs Brand B in driving B&W 802D speakers. I'm trying to gather a bit different info.

I'm ready to change amps and there seems to be some different possibilities available for amp configurations and how the speakers respond. I'm interested in the pros and cons of each.

1st - a large stereo amp (400w/ch) wired direct.
2nd - a pair of mono amps (400w each) wired direct.
3rd - a pair of momo amps (400w each) bi-wired.
4th - a multi channel amp (200w mid/hi, 400w bass) for each speaker, or something close to that.

Does any one of the configurations have a significant advantage? Also, do balanced interconnects between the preamp and amp have an advantage over a good set of RCA's.

If you have some thoughts and care to share your expertise I would appreciate the info.

Thanks,
Paul

I would use ML 33H with separate cables from each amp output.

Please keep in mind your budget and the quality of the amps. In general a $2000 stereo amp would most likely be better than 2 $1000 stereo amps used to biamp or 2 $500 monos.

Having said that the best options in order are 4 monos to biamp, 2 stereo amps to biamp, 2 mono amps and lastly 1 stereo amp.

If your preamplifier has two output sets, you can try two stereo amplifeirs in passive vertical amplification. One stereo amplifier for each speaker and of course you need two full range speaker wires.
If you like the Classé CA400, you can try two in that configuration and your 802D will blow.
Both Classé and McIntosh match perfect with B&W.

I greatly appreciate everyones comments on the amp configuration. I really don't change setups very often so I would rather put in a little extra time up front.

I am going with a bi-amp setup for the 802D's and giving the nod to the ICE amps. The Cullen Circuits multi-channel amp (Wyred4sound) seem to be the best fit and Rick will build what I want down to the binding posts. A five channel amp will provide a 250W and 500W for each of the 802D's and an extra 500W for the HTM2D center channel. Each channel has its own power supply and the output power doubles into 4 ohms.

It's a significant increase over my current amps and I'll do a followup after the amp comes in, gets some break in hours and I do some listening.
