I suggest three circuits independent to the circuit breaker panel. 1st circuit (two outlets) for one amp. 2nd circuit (two outlets) for the other amp and the 3rd circuit for your low level equipment connected to a distribution/power conditioner. I use a distribution/power conditioner to plug all of my low level equipment such as pre-amp, cd transport, tuner, DAC, Phono stage, Turn Table into and that has its own dedicated circuit back to the electric circuit breaker panel. Then two separate independent circuits for each amp. My noise floor dropped significantly (dead quiet) and virtually eliminated any ground loops. You really don't want the amps on the same circuit run. If you are having an electrician do the work anyway, it is better to have three runs as I indicated above. If your TV/home theater system is also there, then a forth run for that system to the electric panel whereby nothing is connected together or mixed. My living room (listening room) is separate from my family room (TV room). So I did independent runs for each room as I indicated above. However, I am about to convert my family room into a dining room and the TV/home theater stuff will be moved into the living room with my 2 channel audio equipment. I will then do another independent circuit just for the TV/home theater equipment.
enjoy
