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!

Aother 10T owner with dedicated 20 amp 10 guage wire circuits and NO problems. Put in dedicated circuits and then come back and tell us if you still have a problem.
I bet ya won't. Having all this stuff on one dedicated circuit is starving your 10Ts on those dynamic peaks.
Its not the equipment, its your power draw and loudness level. It would happen to anyone else with similar gear on only one 15 amp circuit if they played loud enough, too!

The Monster unit does not regenerate AC contrary to its name. Forget regenerated AC, like PS Audio Power Plants, for
high power amplifiers - too expensive. Run your power amps direct from the dedicated hopefully 20 amp wall outlet with a good power cord - I use Granite Audio 560 power cords for this purpose, and I do use PS Audio Power Plants on front end non-amplifier components.
