Ideas for Biamp with mc611 and mc275?

B&w 802 d3

yes 2 amps each side

Excellent point, you have no control over each amplifiers spread of signal to different drivers.

Audio Classics has tons of used gear.

How does one go about bypassing the crossover's? Is this a DIY exercise which I guess requires you to go inside the speakers and remove the filters and have the drivers directly wired to binding posts.   
 

Men 220

Not sure I understand the value of a men 220.  Unfortunately it doesn't come with Home theater capability, and it doesn't provide a graph of your room situation.  It's a box that requires you to test the room and then it comes back with a room correction for all those pressure amplitudes that may be out of sync. Basically it cost $6000 to treat your room, and then you leave it connected to your system. It does provide crossover capabilities but that's a small piece of it I guess.

It does seem woefully over priced.

What crossover device do you use for bi-amp?

I saw your system, is mc275 used for the higher ends?
