I use Alan Maher Designs which in my system consists now of a multitude of various filters, AC duplex and power cords. Have spent many thousands on it since 2010 and to say it makes a "night-and-day" difference does not do it any justice. But plugging everything into filters first is much better than into the wall...there are no sonic drawbacks with it since, like Bybee filters, this is largely quantum-based, no caps or other traditional "parts" that place a much lower limit on how far the noise can be shifted higher into the inaudible range.
Doesn't matter how much current or wattage the amps use, it's all without drawback.
