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.
