Oh yea..that Rotel 1080 looks good, do I have to get Rotel amps from a local dealer? I couldn't find any online retailers...

I looked at the 1080 before, I missed the part in the specs that said "4 ohm compatible" I could find any wattage for 4 ohms, their website and manual only say 200 watts into 8 ohms...nice amp..I check the reviews too...thx!

Respectfully,

I bought mine through a local retail dealer and I believe Wid did as well, I don't believe you can get them online and also the price for the 1080 is $1000 so that may be a little more than what you'll want to spend. I haven't had a bit of trouble with the 1080 during the past four years of owning it.

I know my mono's from Klaus are around 200 into 8 ohms, have no idea what that calculates into my 4 ohm 80's, I can tell you they don't break a sweat at any volumes I push at them.

You guys know the usual rule of thumb is 150% for 4 ohm so the 200 into 8 ohms is about 300 into 4 ohms.

Personally I would still try the Emotiva's, as there are many on their froum running the XPA series of amps with M80s and have had no problems what so ever. I suspect SatKartr's issue has to do with his Yamaha 663 as the preamp, he has popping/crackling issues with it when running the M80s on it's own and I suspect this distorted signal from it was the cause of the XPA-2 shutdown.

I also have had my eye on those M2200 outlaws, I would love 3 of them for the LCR in my system.

Jakewash,

The emotiva RPA-2 is exactly what I want to get, the XPA series are just a little too high to fit under my bottom stereo stand. Going back to my original post, I can't believe this same amp (RPA-2) was so critically acclaimed, (product of the year) yet "may" have shutdown issues. Is there anyone that actually runs the RPA-1/RPA-2 (same amp, just diff casing) with the axiom M80's with no issues?

I'm sure you all have seen the below impedance curve:

http://www.soundstagenetwork.com/measurements/axiom_m80v2/impedance.gif

Where the M80's dip into 3 ohms at 40-50hz, I still find it hard to believe an RPA-2 would shut from this...but I guess it's possible...

According to the graphs I've seen, can't find them right now, the Axioms do not go below 4ohm, even looking at the graph you posted, it does not go to 3ohm, I overlayed a straight line from another Windows tool and it is right at 4ohm.

I've my XPA-2 run my 2 M80s as mains for about a month now and have not experienced any shut downs. Before buying the amp, I asked Emotiva about the shut downs and was told to connect the M80s in stereo mode, not bridged. It was a few steps up in soundstage and clarity compared to the Behringer 2500 I was using to power the M80s before. I guess the Karma police has been nice to me. Hope this helps.

Hi DDuval

Have you thought about going with a used amp? You can get a used Bryston 4B, 250 watt into 8 ohms for around $700 to $800 on Ebay. Bryston amps come with 20 year warranty, and are pretty much bullet proof. Easily 4 ohm stable, it will probably live longer than all of us. I would probably sleep better at night owning a used Bryston than most newer amps on the market today with warranty.

Just a thought.

That's exactly what Nick at emotiva said...DO NOT run in Bridged Mode and there are no problems, and they can also be stable with dips into 3 ohms. The ones with shutdown issues were run in bridged mode, of course "according to him"
