Thanks everyone for their input, I'm very confused getting feedback from both sides. I just wish you guys could do the talking for me.

I think I'll hit a bar on the way home and have a few Guinness beers and ponder what to do next, arggg. Maybe I'll send it back and get one of the new Denon's with MultEQ from Odyssey.

For starters, your advice is why I had 2 electricians from two companies come out and check our house. They both said there was nothing wrong with the electrical box or ground in my home. It is to code. The problem was resolved by Emotiva by placing a cap on the regulators that operate in the ghz frequencies.

I live close to an airport and the signal tower operates in the microwave frequencies, which was interfering with the amps, they made it right again, and the ground was not to blame.

Your still not providing any facts as to why you think the amps are defective, versus just being pushed to their design limit. 119dB's at 1 watt 1 meter requires 256 watts. If the $49 Radio Shack meter is not as accurate as the Audio Toolbox meter, which I think most would agree, then peaks of 20dB's would refer to ranges beyond 300 RMS, in which the amps protective circuitry would be introduced.

I just need to decide if I can live knowing the amp will shut down if pushed to +4 on the volume knob, or look for something else.

I am not the only one having this problem, if you follow other forums. Otherwise, I would say yes I have a defective amp. Other people with 4ohm speakers from Onix, NHT, and Axiom are having the same issues when pushed to similar levels.

Thanks, anyway.

Randy I am not going to tell you that the amps are defective. To be honest I don't know one way or the other if they are defective or not. The one thing I can tell you is that they do not meet your needs or expectations. That alone should be enough that you would send them back and seek out other products that may be better suited to your listening environment. I think that your Denon is one of the best HDMI receivers out there at the moment so I don't think you need to replace that unless you need more HDMI inputs.

It would be nice if you lived closer so I could lend you my ATI amps to try out to see if there was any difference. Good luck with your decision.

Well apparently I'm none too bright as all along I thought Randy was using the Denon 2807 which has HDMI when he actually has the 2805. Still shouldn't make any difference amplifier wise though.

Thanks for pointing out my faux pas Randy and good luck with whatever you decide to do.

That's one thing the Rotel RB 1080 has, it has a 1.2 KVA transformer.

How large are the toroids in the Outlaws spread across 5 or 7 channels? I know each amp on the mps-1 has its own 350VA Toroid or 2.45KVA total for 7 amps.
