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!

Dan,

I used to have on one Dedicated 20 amp outlet with the rest 15. Because a reconfiguration of my system I went ahead and installed 5 dedicated 20 amp circuits for my system. I just finished setting up my system this morning using the 10T and CC3B. I went from the PM1000 to the PM2000 20amp unit. Even prior with the PM1000 I did not have a problem cranking up the volume. I have changed a number of items in my system in the past 3 weeks but I am sure the PM2000 was the biggest bang which created tighter and very controlled bass with more air to the midrange and still no sign of strain or cut outs.

Maybe it is your in coming current?
