Connect 3 High Current Amps to a Power Conditioner

Thanks all for the wonderful and detailed feedback. I have a lot of fun homework ahead for trying out these different combos laid out. I also realise that the ideal is to have dedicated branch circuits for the amps. A little consolation is that I have a small-medium room with 8 ohm mains. So I wont be powering these guys all the way up and therefore am looking for more clarity in the system.

My 2 fronts speakers have power rating of 250watts (center 200watts) and my thought process is given that resistance and current are inversely proportional (P=IR), I guess I wont draw too much current given that I dont crank up the speakers too high. I am new to all this so what I am saying could be completely wrong.

Also the manual from the adcom does have the following:
It is not recommended that you connect the GFA-555ii into a branch circuit on which other appliances are used. Since conventional household branch circuits are often limited to 15 amps, when the gfa-555ii is used in conjunction with other appliances on the circuit, you may find the current available for the amp is insufficient; particularly in systems using very low-impedance, highly reactive loudspeakers

I will try out the sub plugged in to the outlet with the amps in the PC and report on the quality/impact. Also, as FYI, the PC I am using the panamax 5500 with AC regenerator.

I have a 5510 in use for the past 10 years or so. Great unit.

First, the 'regenerator' part of the logo refers to a small isolation transformer.
Follow the 'schematic' on the units top plate and connect all your low current and digital stuff to this.
I use another outlet for my TV.
In years past I experimented with the HiCurrent outlets and found them to stifle an amp. Even my moderately powerful Rotel RB-1070 of 130x2 driving fairly low sensitivity panels of 4ohms was lifeless. This combo never went above about 5 amps on the supplied meter. Plugging the amp straight into the wall helped a lot.
These days, my amp goes into its own circuit along with the sub. I have a PSAudio Soloist outlet which has some noise reduction / surge protection features.
The Rotel is long gone.

Dedicated circuits and a Torus PIU.

sigh, so many gurus. i think the best is still to try out for yourself.

That's exactly it,AUDITION for YOURSELF,then you will know.
Home audition is best,your gear and your room.
Most audiostores will let you home audition if they know you
are going to lay down some coin.
