If you do a search on "emotiva", there have been many threads. Some Axiom owners have been happy with their products, I was not so lucky. If it was me and you are using m80's, I would look around as much as you can. Granted, I owned the MPS-1 for 3 months. At the time it was their king of the hill amp, and suppose to be stable down to 1ohms. The amp kept shutting down during explosions during action movies, or when I would turn up some rock music from time to time. Heck, my Denon 2805 never shut down even at higher levels.
Does you room size and listening habits justify a seperate amp?
