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!!!!!

Sbruzonsky is correct. Monster is usually good to stay away from anyway. But with the current draw from your amp, you would need a very high powered AC regenerator which are very expensive.

I'm using a Foundation Research LC-2 in-line power conditioner but even that is only rated for 200 or 250 wpc so I'm suffering just a bit in that it weakens the bass ever so slightly. But it works wonders otherwise and I don't need an aftermarket power cord since it is 'in-line'. On top of that it does more that most power cords can do and costs about the same as a very nice power cord.

If you having problems with your ac lines due to excessive loads, adding any kind of ac regenerator is only going make it worst. The ac regenerator can not give you any more power than what the circuit is capable of putting. The regenrator will actually contribute more load since it's not 100% effcient.

Very good point, Sfstereo.
