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!

Ahh, dudester, what ARE we going to do with you!!!!
I'd like to be a fly on the wall during one of these sessions when the amps clip. Are/were you the guy who directed the planes off the carrier catapult?

I have 33H driving 10t, one of the "big power" specials I had used in the past was a set of Classe' M-1000 monoblocks. M-1000= 1000w/@8ohm, 33H=150w/@8ohm. The 33H drive the 10t's considerably better than the M-1000's did.
I have never had a problem with either the amp or speaker reaching it's limits. I'm not saying the Rowland isn't good, but it may not be the match you may think it is.
Keep trying, I did, and I'm a happy (but broke) guy today.

Forget the power regenerator stuff, the amps draw way too much. You just solved your problem when you mention that all your stuff's plugged into one circuit, can you say bad, very bad?! I'd be on the phone to your favorite electrician, and quick.
