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!

Beemer!
This is it? With all the gear plugged into one outlet?
Plasma, a pair of SW-12 subs, a trio of Roland 7's, a citation 7.1, LD, DVD, preamp, processor, projector, screen, and of course a couple of line conditioners?

This is it? How simple. I understand this is going to make a huge difference.

Do any of you know threads that discuss what types of lines, size of cables, etc that should be run? I understand a dedicated ground should happen, what else should I do?

Thanks to all that have responded (again) to this post.
In deed, contrary to your thoughts, I have talked with Mike Kelley, and indeed, he felt more power from a 2 channel amp would be better served than a lesser 4 channel, biamping.
Thus, he thought the Classe would be a good match, and my thought was, the Rowland would not be any worse, if not better.

In deed, I do not listen to music this loud very often, but I do like to on occasion, as I imagine everyone here does.

Also, I appreciate the 'learn about audio' comment, nice.
I think that is what I am doing, and if there was a clean answer to this question, not only would I probably have know the solution, all the responses would be identical.

That said, I am starting to feel, the circuit is the issue.
I am running BOTH amps, as well as ALL of my gear off the same 15A circuit!

Hey, great suggestions, maybe it is the circuit!!!

Thanks, and I will search that avenue. Let me ask this, would a power regenerator, like the Monster AVS-2000 help?
