McIntosh MA2275 Bi-amping

I already has a MC275; any suggestion out there
1. if I were to acquire a MC2275 integrate amp (essentially a C220 + MC275) then bi-amp; or
2. is it possible to do a bridge mono on both (MA2275 + MC275) to get over 150 Watts.
I think option #1 is a likely possibility. Suggest you contact McIntosh technical support... they are always very helpful. Let me know what you find out as I previously owned the MC275 and currently own the MA2275.
