All I can say is that I have a receiver (not a dedicated power amp), that is only rated at 120W. It's the Denon AVR-3806. It has NEVER tripped out on me with the M80s. 2 years running, 1/2 inch clearance over the vents. I have never had a problem.

I've had my Rotel amp for going on 6 years, without any problems.

My LPA-1 ran my M80's for a year without a shutdown. Since New Years eve I have been running the XPA-5 without a shutdown. I am thinking about getting the XPA-2 maybe I should'nt!?

Mistico, welcome. Your 1400 can certainly drive the M80s to a very loud level. Despite the Emotiva comment, the M80s are in fact a quite easy load as speakers rated at 4ohms go(possibly a 6ohm rating would follow typical rating practice more closely). You'll find out whether the 1400 drives the M80s loud enough and long enough to fit your normal(almost any amplifier can be forced to shut down)use pattern. There's no good reason to assume that it won't be entirely satisfactory and go off looking for another amplifier at this time.

Thanks, Johnk. I actually joined the forum in 2004 but haven't posted since. I remember many of you from back then. Good to see many of the same folks still here. Did the forum undergo a rebuild? I had to reregister.
Back to the thread now...:)

Why did I have a feeling that when someone asked about impedance graphs of M80's, that Emotiva would come up again. For the ongoing record, my M80's work perfectly with my Emotiva LPA-1. Zero problems. None. My system will play louder than I can tolerate (>105db, from my seating position), and sounds lovely. So there is at least ONE example of M80's playing nicely with Emotiva amps. My den is proof. All are invited over to listen. Free beer even. But of course, others have had problems with M80's + various Emotiva amps. If we grant that both Axiom and Emotiva are being truthful about their products (which I believe they are), then every Emotiva amp should be perfectly capable of driving M80's. But they can't. So that means that either Axiom or Emotiva has a Quality Control problem. Based on my experience with the Emotiva LMC-1 prepro, I'd be betting against Emotiva on that duel. In my company, if we discover a problem with one of our products, we buy it back from the customer and test the living heck out of it to figure out exactly what happened and under what conditions. We solve the problem. And then we improve our product so that it never happens again. It's a shame that Emotiva can't or won't get to the bottom of this. But at this point in time, it's a finger-pointing game between Axiom and Emotiva. Of course we're here, so we're mostly going to side with Axiom. And why shouldn't we? Alan, you are exactly right - other 4-ohm-minimum amps don't have problems with M80's. Sooo..... And yes, I'm sure the A1400 will work perfectly with M80's. It better, considering it's a $3,850 amp.

Does Emotiva use a different design in their power supplies (or in general) than say Denon, Harman Kardon, Sherwood Newcastle etc which have a history of having no issues with the M80's?

Wolf, I believe the amps from Emo that have had issues are the ones that included a waveform limiter circuit. The MPS-1 was the first to introduce this special little nifty pos circuit. I believe the XPA series also have this nice little wonderful high tech option that will shut down your 80's.
