I'm going to be purchasing a new speaker setup fairly soon. I was looking at the Epic 80, but both of the reviews on the Soundstage network mention that the M80's require at least a medium-sized room to avoid boomy bass or overly bright treble. My room is 18 x 13, with one side wall open.

Should I look more closely at M60's as the mains instead? What difference can I expect in terms of output and matching, assuming the VP150, QS8 and EP350 stay the same?

Thanks
