what do you mean biamp using m72? Are you talking about adding another amp...or do you mean bi-wire?
you can but to get the most benefit of bi-amping, you'll need an active crossover that goes between the preamp and amps. i use a first watt b4 crossover for that purposes. it also requires a lot of listening to dial in the XO to get it just right (a lot of listening is not a bad thing!).

bi-wiring doesn't have much benefit.

YMMV.
It's not as easy as it sounds. You have to get everything just right in regard to matching the two amps, and I was never successful.
