looks like you are well on your way to building one heck of a system. i have the M60's, 150, and QS8,s being pushed by the onkyo SR701. i couldnt happier with this set-up. i have yet to really crank it to the max power of the receiver cause its just too dang loud. those 80's should give you a powerful, yet clear wall of sound. i think you will be more than satisfied with your results.
