LOL No question is dumb at this point, yes, after weeks of tweaking between tests, I'm back to running the M80's for the front and center channel in large mode, this final decision was aided by Alan, as he agreed with me, with the M80's and my ear, I can not detect any big differance, and it just seems to be a tad better when set to large. Besides, got tired of trying to compare large/small setting. <g>

Also becasue of using the stero 7 mode for most of the music listening during the day well being all over the house, I have found I do need amps for rears same as for the fronts and center, kinda of hard to explain, but the way the speakers are set up here, and the mere voulme of area, need a lot of power.
