A little more on my "blinking lights". It lasts less than half the length of time than it would take to blink your eyes. The amp "clicks", speakers give a small "thump", and lights concurrently blink about one second after I push the power button. At times I can't even see it; but my wife claims she always can. The amp the 755 replaces was a 1200w amp. We never noticed any issues with it and the electrical load. Plus, I had it on a UPS (surge only outlet) with the rest of the components.

Yesterday, I connected the 755 to a separate circuit from the rest of the audio/video components (the components were within six feet of outlets from two different circuits). The only thing that shares that circuit are some recessed foyer lights that are normally off.

Yes, lights on other circuits do "blink". However, I can't believe the panel is close to capacity. The main is 200 amps and we have gas heat, stove, and water heater.
