When I first started to make comparisons, I could hear a difference from M22/sub vs. M80/sub, but recently during some more testing there wasn't as much difference, I suspect the first round findings were due to poor positioning of the M22's.

I still like to think that there is a difference and with my recent amp testing I can say for certain, in my room, the M80s/no sub, sounded better to me than the M22/sub combo did when the speakers were run with the A1400-8.
