Well i'm in GA so listening to these is probably out of the question.
His coments about the sound stage is what bothers me. But agian, he did not say he tried to move the speakers around, try different spacing from the back wall, or anything else. He did say that the M80's took all his poweramp had to give. Which the underlying note to me would be, he really did not have enough power, for his room size for the M80's. Plus the speaker placement(how far off the back wall) may effect the soundstage for the M80's. I can by some of the bass comments since your dealing with 2 8 inch speakers VS the smaller speakers in the M80, but againg , may be due to power amp and speaker placement.
