Are you using any power conditioning in front of the power cord?
I would address that if needed first from a clean power perspective by trying a power conditioner perhaps for everything except the power amp at first and then see how everything else does from there. IF the power conditioner is beefy enough to deliver enough current to the power amp, then yu might try it with the power amp perhaps as well as an option.
