I know the Yamaha has pre-outs, but does the Sony have pre-inputs? Very few receiver have pre-ins and without them bi-amping really can't be done, at least not properly. The Yamaha would need to have pre-ins, also.

I'm not familiar with the M80s, do they have separate crossovers or will you need an external x-over? Although you really should use an external x-over regardless of the speaker. It's just a question of whether you need to remove the internal x-over.
