Yeah for sure. Just throwing out ways to try and solve the issue.
I can try another outlet. I actually have construction going on now so may be able to request a dedicated line being put in but I need to bring this up to if it’s something they’d even consider.

That is not true since an inverter can be built much different from an amplifier (because it operates on a very limited spectrum of 50 to 60Hz). At bare minimum, an H-Bridge configuration of some switching component (mostly MOSFETs for efficiency reasons).

Nothing is absolute. It’s all design and parts matching/quality. I don’t know how exactly the PSA regenerators do what they do (aside from the fact that they’re a single frequency amplifier) or how they measure 
If they have 0.00001 volt of DC, it’s still DC. But it’s so low it doesn’t matter. The proper question is, how much matters and does a piece of gear do better or worse. I have no idea what the answer is.
An ideal transformer has 0 resistance to DC in all coils.
A real transformer due to the conductor will have in the low mΩ resistance.
Thing is, any transformer on your local grid will add to that almost 0 resistance. So to see even 10mV would mean several thousand amperes flowing through an entire neighbourhood and local substation.
Been watching a couple of PS Audio videos on the topic of DC. In this video at the time I’ve shared he says that there is a dc blocker built into all of their Powerplants: https://youtu.be/sDE2uekqLsA?t=590.

That’s good to know; that video was useful, thanks!

Also I’ve put in a request to the people doing construction at my house right now and I may be able to get a dedicated outlet / circuit for my audio gear. It’s good timing that I’ve been investigating the power in my system as the wall behind my audio setup where the wiring for the outlet is is exposed. Will update if they are able to do a dedicated line and if that helps with the transformer hum I’ve been having.

The dedicated 20amp circuits i had installed in various rooms when i had my home built have been the most value added to my stereo. The lines are as clean as possible, there is zero draw on them from anything else ever being used in the house, they are completely separate and well isolated from noise that could possibly be induced by any appliances. I am currently having some remodeling done and taking the opportunity to have the electrician go through my entire service, swapping in fresh breakers, completely re-tightening all the wires, bolts, nuts etc in the main panel and we are even considering swapping the entire panel to isolate the stereo circuits on their own buss bar separate from the rest of the house before we tap a whole house generator in to the panel.

So my dedicated line got wired up but it’s not connected to the breaker panel. They need to get the wiring inspected or something as part of the construction going on. @NickMimi you mention having 20amp circuits, is there a reason to go with that over the usual 15amp circuit? Also is there a benefit to using outlets from PSAudio or JPS labs or just any hospital grade outlet?

My big amp needs a 20 amp circuit.
The better the grip of the actual outlet itself the easier it is to use these expensive heavy cables. Upgrade to whatever point your wallet feels comfortable. I do not see better quality materials hurting anything, if you hear a difference or not is up to you to decide.

Makes sense, I just have a headphone system so I think the 15amp outlet will be fine. I’ll probably connect a better outlet at some point as I do have a hospital grade outlet laying around. But, I haven’t had issues with cables falling out of the walls yet.

It’s not so much a matter of cables falling out of the wall. The better grip also provides a better connection - lower resistance. Conceptually/technically it’s a good thing. Aurally? I have no idea lol

My dedicated line is finally hooked up and I just connected my audio equipment back to it today. I’m still using the Furman Elite 15 Pfi as a conditioner / surge protector. I still hear a little transformer hum but I think it’s less pronounced then it was before. I just glad to have a clean slate to start from with power. I’m still interested in the PS Audio Powerplant and may check the entry level version out probably after I upgrade my dac.

Hmm, looks like this PowerPlant Premier still hasn’t sold yet. Does anyone have any thoughts/impressions on this particular model? I don’t know anything about the older model PowerPlants.
EDIT: Also, for anyone else looking, it’s $800 /before/ shipping and PayPal fees, and these things are pretty heavy as far as I understand, so shipping won’t be cheap.
General question to any of the owners: Do y’all keep yours on all the time?

I personally do not unless I know I will listen again in a few hours. Otherwise, I turn mine off but mainly because I have a ton of tubed gear

I leave mine on unless my power is going out or something.
The devices plugged into turn off when not in use, but that’s just what I do with tube gear.

What does the manual say?
My question was out of curiosity, not being a smart ass. I actually just perused the P10 manual and it found nothing about turning it off or keeping it on.
P3 manual states “suitable for continuous operation”, honestly I couldn’t imagine someone building a device like this that wasn’t. The designer has no idea what’s going to be plugged into it.
