I give UP Aerial 10Ts and Power Amps

Ok, about 30 days ago, I ran a post stating my Citation 7.1, a 4 channel 210 x 4 (biamping my speakers) started cutting in and out at VERY loud levels, probably +100db, give or take. Everyone pointed to larger amps, that the speaker, a 4 ohms load, could take anything I threw at it.
Well, I took that word, while keeping my Citations, and threw a set of Jeff Rowland monoblock 7III's at them!
The babies, definitely high current, 350 into 8 ohms, 700 into 4 ohms, and a whopping 1100 into 2 (not that we are going to 2, but I suppose it could drop) ohms. That said, it happened again! WHAT GIVES?

It did this with the Casablanca, the Citation 5.0, and tomorrow I will be with the keeper, the Proceed PAV/PDSD combo. NOW, what is causing this? Could it be the speaker has a cut off to prevent any clipping, could it be the power in the house hits a wall and can't go anymore, could it be cables, power cords, what?

Or, dare I say, could I have just hit the limits of volume for a home and this set of speakers?

For what it is worth, I do not listen to things this loud, ever, or RARELY, but when changing pieces, I do PUSH to know the limits.

HELP!!!!!

Frustrated home theater guy trying to learn more about 2 channel!

Just for the record, I was the person to who sold Dan (PorscheCab) the Rowland 7s. As he drove up to my home in his van I knew he was coming as I heard his car stereo from about 4 blocks away!! (:-)

While I have very efficent speakers (Michael Green Chameleon 3s), I agree with Stehno and had each Rowland on its own 30amp Dedicated circuit. In fact I have 5 circuits, 1 for wach amp, 1 for a preamp, 1 for analog, 1 for digital.

Dan, perhaps, you need to get an electrician in to work on your AC supply....give me an email and I put you in contact with the person who did mine.
