OK, I finally got my M3's connected in the family room with the inwall wiring and ran them thru my old Technics amp, using a cheap JVC combo DVD/VHS player.
First impressions were very laid back but after adjusting the bass and treble on the amp, these are great. My son watched a little Star Wars before bed last night and ran the sound thru them. I have to say for a smaller room the M3 would be fine for HT. The rumble of battle cruisers and hi pitched sound of lasers came thru clear on them. Great speakers.
