Wow, thanks for all the replies!
I'm considering a P3 for my overseas system where I have 110v in my house on "camp" (like a base), surrounded by 240v lol. A little city running on 110v - not just my house literally.
I have a few issues here I hope the P3 will cure, rather than adding an isolation transformer, although those seem like a good option for current delivery. I have been considering a Richard Gray Pro 400 20A.
I currently own a cheaper, smaller 100w P100 AC regenerator which I can only use on my DACs as the MT and Rachel draw to much power and overload the transformer in the regenerator.
Right now, I don't have a dedicated line. But I do have a unique 20A circuit running direct to listening room from breaker - 3 outlets - so just some lights TV and HIFI.
My dishwasher was spitting a harsh buzz (like a monster ground loop) up to my tube amp. Turn off dishwasher and all is good. I re-grounded the dishwasher and it's very very very faint now when running.
In general, the power here is stable but iffy imo. A UPS will show pretty stable voltage so I'm not sure what the problem is? Surges? Light bulbs burn out all the time. When I returned from repat to the USA last year, my subwoofer had a blown cap, but no blown fuse. My neighbor just blew his MLs, and a BRAND NEW Classe preamp. And he had a 1K power strip.
My system consists of:
(2) DACs pulling 20-40 watts total
(1) 6w/ch Rachel EL34 tube amp pulls 70-90watts
(1) Mini Torii on the way
(1) 250w subwoofer with plate amp
I asked PS Audio:
Does the P3 isolate when doing its AC>DC>AC conversion? Or is my problem of bad shared ground ? going to let noise slip through and other means (dedicated line, grounding rod) are needed?
Quote:"Unfortunately, the P3 does not offset DC coming back onto the line which the dishwasher could very well be doing. Nor does it resolve any ground loops.
They do make cheater plugs that might work. Contact Music Direct. They may have a recommendation or solution if that’s the case."
So my plan was isolate but now I'm thinking of selling the small regenerator and buying P3 again, so I could run all my components on it, not sure! One of my friends uses:
