Like Axiom, Emotiva has a 30 day return policy.If you feel it makes a difference, great.If not you send it back.Myself and my audio buddies have done several AB comparisons with my reciever and a friends reciever both running on their own and with my LPA1 hooked up.To us the improvement was quite noticeable.But you'll have to hear for yourself, every situation is different.

Does anyone here use a NAD amp on their M80s?

They have and work great, no problems.

I just got off the phone with Emotiva, and the support person(Chris I think) told me the same thing, that M80's dip down to 2.6ohm and that causes the AMP to go into protect mode. The only reason I was looking at the amp is because I have M60's and I'm getting a set of M80's and I'm not sure if my RX-V1400 can drive them well.

It would be nice if someone asked them the basis for their statements. Back when I was having issues, Lonnie, one of their chief engineers had never heard of Axiom. What is the basis of their statements, sounds like smoke of callers a$$'s.

There's a fairly easy way to test their claim. Buy something like the IRP1000: http://www.isotekcorp.com/dataSheets/dataView.asp?ds=irp&orderURL=It's a power resistor that is capable of handling 400W in free air, and has settable inductive (imaginary) and non-inductive (real) loads. Set them both to around 2.8 ohm (the square root of 8), which would result in an impedance of 4 ohms with a 45 degree phase (half real, half imaginary since impedance equals the square root of resistance squared plus reactance squared). Hook it up to the Emotiva and see what happens. If it trips, then the Emotiva has problems with a 4 ohm impedance load. If it does not trip, try slowly decreasing the resistance and reactance (non-inductive load) to see where it does trip the amp. Steve

Electro-Geek Throwdown! My money's on Steve. I'm with Randy; unless Emotiva got completely different information FROM AXIOM than has been published elsewhere, or they independently measured M80's and got different results than Axiom publishes, I think the explanation boils down to "it's not us, it's them. And here's some made-up stuff for justification".

So is this a problem with all XPA2 amps or just a select few? Do other Emotiva amps also have issues with the M80s?
