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.
