Randy,
Although you have had no intention of spreading negativity about Emotiva, I have to admit that I am no longer looking at their amps for a future purchase.
And you know what? I am HAPPY that you had your problems, it gives them a chance to fix whatever is wrong to make their product better. But at the moment, their MPS-1 line is not all it is cut out to be (perhaps with certain speaker models and crossovers like you said).

I was going to pass up this opportunity to keep my mouth shut, but I want to provide one balance point to what Robb said.
I like this thread, too. I learned (and re-learned) a lot.
As a consequence of the superior customer service Emotiva provided Randy, my ownership of M60's and several other factors, I am considering Emotiva products more than ever.
Now, I don't want in any way to discount my friend Randy's experience. I can't imagine how disappointed he must be. At the same time, I'll echo Peter's observation that Randy's SPL needs in his environment seem to be simply beyond what the product is designed to do. As to the Denon seemingly not having the same problem, I'm not sure there is a way - in this instance - to measure the THD, but I'd wager that the Denon keeps running (and distorting) when the Emo shuts down gracefully.
I want to support and encourage Emotiva's participation in public forums. My opinion (as a prospective rather than current client) remains that their products deliver a decent performance/value ratio and that their hands-on approach will continue to yield even more impressive results.

Regardless, I'm still quite pleased with my LPA-1 & M80 combination.
Volume on my AVR maxes out at +12. I've been there once with the LPA. Playing relatively quiet solo piano music in my 3400cu ft room, that was pumping out 105db sustained with peaks at about 110db from my sofa, 11' away from the speakers. The amp was definitely starting to clip, and my head hurt. I backed it back down to normal listening levels within about a minute. That's supid loud. Hearing-damage loud. I don't know why I'd ever want to go that loud. It's not music anymore, just noise.
<bad car analogy> It's kind of like my car. The speedometer goes to 160mph, and I know that the Euro version will go 150mph+, but here in the US it's governed to 135mph. I suppose I could be mad about it, but it's just unused potential. </bad car analogy>
However, in Randy's room, more than twice the size of mine, I can see where you might need more serious amp power.

I'm going to pick up a piezzo tweeter from Radio Shack to run the test Lonnie told me about. This will tell me when my Denon starts to clip.

Hutzal, it's quite unfair of you to state that the line is not all its cut up to be. It's now been proven that it WAS producing the advertised power. Once Randy took it one or two notches PAST, it shut down. Sure the Denon went higher, but with the distortion he was experiencing, I'm sure it sounded like fecal matter.
As I stated before, the same thing happens with my two. When pushed, the Luxman stays clean until it shuts down, and the Yamaha doesn't, but sounds like crap while trying to keep up. So what's the point of even trying?
I will agree that it's frustrating. It sounds so clean that you want to push it higher, but then [click], it's off. We've effectively reached the limit of what the amp will do.
As Randy found out with the lower rated receiver, it could go just as loud, but with tons of distortion. But again, he effectively reached the limit of what the amps would do.
So what would you rather have? An amp that shuts down and protects the speakers, or one that can go past it's limits, distorting, and possibly taking out tweeters in the process?

If the new Axiom amp passes Randy's requirements, then it should be a real selling point.

I think Randy ought to be a beta tester for it.

I would love to be a beta tester. ps: I'm tossing the idea of checking on the RPA-1 2 channel dual monoblock amp from Emotiva. It would be interesting to see how it would perform. randy
