John, what you say about power factor correction is completely accurate and very much makes sense. There is a many ways to do it BTW. You can do it with caps compensating the inductive load, you can do it with filtration or you can add active SS circuit that would engage the caps at the very specific time and kind of fake activeness of the load. They all work very well and for sure will do benefit the efficiency of your home grid and make you to draw less electricity. None of them work perfect (unless you are spinning an idle synchronous motor purely for the sake of power factor correction) as load go up and down and amount of current is not stable, the hot tubs pumps and heaters goes on and off, the freezers go on and off, the thermostat turn ether AC or boilers, lights and everything else goes on and off changing in power factor landscape. (BTW, I do not think light do as they are pure resistive load). In case you have a SET amp then you for sure can heat it up as it thermos-stabilized and begin to draw very constant current then you can implement a perfect power factor correction for this amp only. Here however we face a dilemma: adding a cap to AC line always worsen sound, primary the very lower bass and LF’s dynamic. 0.2-2uF was very auditable. So I do not know if I welcoming the idea of power factor correction for audio. You might argue that I already have plenty of caps siting on my power lines and I would not disagree with you but I only presume that less would it be the better sound I would get. Saying all of it, I do think that it might makes sense to play with PPC on the PP3000 source side.

Regarding the ferrite packages on the incoming mains supply. That was a brilliant observation. I do float ground on the supply side, only on load side. Still, the idea of differentiating of ferrite rings between the power cord’s hot, neutral and ground is something that very much worth attention.
