Connect 3 High Current Amps to a Power Conditioner

I tried many power conditioners as well...none of them was an asset.

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.
