Welcome aboard, you'll love your Axioms!!!! How big is your room, I assume pretty large since you have the M80's? They will blow you away
Anyway, you will want to make sure you get a receiver that is capable if driving these low ohm m80's. I know a few of the Axiom techs will tell Denon and HK will have no problems. There are a lot of people on this forum that have M80's so they can shed some more light on the topic.
I love my Denon 2805/M60 combination, it gives me all the sound I'll need for a long time...
