xpa5 + m80v2's here with no problems only sonic bliss....

TURBO-I have both EMOTIVA XPA 2 AND XPA 5 BOTH amps. I discovered distortion and clipping issue these amps. This only happened to me when I select my listening DSP modes on my Denon to 2 channels-Direct and PureDirect (2 or 7 ch stereo, dolby digital are OK). For the XPA 5 I can raise the the volume 3 db high than XPA2 before I get into the distortion. Try yours playing a heavy bass music...rap or pop. I am returning my XPA 2, keep XPA 5 for my c/surrounds and look into other amp for my M80.

I got rid of my MPS-1 Emo years ago, they kept shutting down. Until Emo can show me their amps can drive an efficient speaker like the m80's, I won't go back. GS, the 80's do not go below 4ohm across the freq range, no matter what Lonnie or others on the Emo forum will tell you.

When I first got my RPA-1, it had shut down a couple times on me, as I've mentioned on this forum many times. When I contacted Lonnie, he gave me the usual "M80's dropping below 4 ohms talk". Ever since I removed the side panels from it, thus allowing more ventilation, it hasn't shut down on me since; and I play my music very loud sometimes.

Now, let's hope that I didn't just jinx myself!

I am running the XPA-5, XPA-2, and the UMC-1 (before that an onkyo tx-nr1007 and before that a yamaha rx-v1800 with a LPA-1)with my M80'2 and the sound is amazing and distortion free. Plenty of headroom. I will say if you are getting and XPA-2 to call them and let them know you are using it with M80's. I went to Emofest last fall and I was very impressed.

The UMC-1 is built like a tank, but still has a few bugs for me after the first firmware update. Although the firmware update resolved a lot of my issues. I love the sound quality it blows away my last two receivers. YMMV but I think if anyone is interested they should try their products. I have been happy with all four Emotiva products I have owned and I love my Axiom speakers.

I am sure it is disappointing to those that have had problems with the M80/emotiva combo I have just not had those issues.

How are the 2 ch music and movie SQ with UMC 1 compare with AVR? I am on a waiting list to try out their UMC 1. I heard it blows away Onkyo prepro 886 and very good with 2 channel music. Also, how is the Torino faroudja video processor? Last what did you do with XPA 2 for your F/R not getting distortion and clipping issues. Like I stated in other thread I get these 2 issues during PURE and DIRECT music modes, in rap or heavy bass pop. Have you try these two music modes?

And my amps are connected to a dedicated 20 amp circuit.

The Onkyo 886, among others, is a very good Pre-Pro. Realistically speaking, considering the fact that, today, only a "handful" of companies manufacture the processing chips and DACs that go in to most if not ALL of much of recent AVRs and Pre-Pros, from my twenty years experience in the CE business, I always look at the idea that something "blows away" something else as being a "slight" exaggeration.

I cant comment on the sound quality of the Onkyo 886, but I could hear an improvement in detail and sound stage on music compared to my Onkyo tx-nr1007. as far as video I use passthrough and I dont see any difference between onkyo and the umc. Movies sound better as well. I dont think the difference is as noticeable as adding the xpa amps was.

My xpa-2 has different resistors on the protection circuit which makes it less sensitive. I have driven it pretty hard with no shutdowns.

As far as heavy bass. I will have to try them again without the sub. I would imagine that heavy bass at some level would be too much for the bass drivers in the M80s. They do pump out quite a bit of bass but they are only 6.5's. On my system I am sure they would bottom out before my xpa-2 will clip. On higher frequency bass or with my sub it is not a problem.

You stated to you have diff. resistors...is that a special order from EMO to have it changed out for you? I have the XPA 2 for 3 weeks now. I do like the EMO amp. It perfectly match SQ and dynamic heardroom I wanted with my AXIOM speakers. Beside the Distortion and shut down this would be perfectly paired.

Yes I picked up the amp at Emofest and they changed the resistors and shipped it to me. It should only keep the protection circuit from triggering as easy not sure about distortion/clipping.
