Advice re PC for Plinius amp


I have a a Plinius SA-250 and I suspect the massive transformer is creating noise on the power circuit - maybe DC, but I don't know that for sure. Even though I use dedicated 20 amp circuits, all the gear is connected / grounded to this source.

My question is: are there any PC's out there that can block DC or has anybody experience of PC's with Plinius amps and reducing hum back into the system.

Do you have a ground toggle switch on the back of your amp?
Do you hear any difference when you use it?
