Hello Nick20,

First off, welcome to the forum \:\) .

There have been some documented cases of some Axiom owners having shutdown issues with certain Emotiva Amplifiers (with the m80's) while others have had no issues (I forget the models off the top of my head). Some of the people that have had issues with Emotiva and the Axiom M80's are regular forum members here so they can provide you with better and more detailed information than I.
The most popular match with the M80's are the mid-higher end Denon avr models among the forum members here.

Good luck in your speaker journey!

Cheers!

I’m armed and I’m drinking. You don’t want to listen to advice from me, amigo.
