I'm probably not a good one to comment here, because the only other speakers I've had any experience is some Bose 901's back in the 70's and a HTIB before buying Axioms. Also, I don't have the M80's but I have 2 sets of M22's that I use; click on link in my signature line.
Watching movies at home is much more enjoyable that watching them in a theater, IMO, even though my current screen is only a 37 inch tv. I am in the process of converting a lower floor at home into a small theater with a 100 inch projection screen that will have 3 M80's behind it.
That is a sick array of speakers you got all on your front sound stage!
