Best place to live for good quality power

The location for clean power is not as important as how you bring it into your listening area and how separated it is from the rest of the living quarters. Another expensive endeavor, but what isn't in our hobby.

Might be a stupid question from lack of knowledge on function. All the people who are running battery power for clean low noise sources. Does the power not vary or degrade as the battery powers down? I look at a flashlight that gets dimmer and dimmer as the battery gets weaker. What am I missing here. Not being sarcastic would really like to know.

@sgreg1 Fancy modern battery power supply (like "Jackery") has regulators and complicated circuit that keeps that from happening. Because they are designed to power digital circuits, the power must be tightly regulated. But the true affect on audio is known only to the users. (I dont have one)

Interesting responses.

Seems physical infrastructure is most important. A rural location with rusty spider-web equipment that technicians have put decades of bandaid solutions on which will catch the forest on fire probably sound worse than a dense city with a new supply. Or maybe finding just the right location in the world with vintage power company gear gives you the right sound lol. possibly.

I live a few blocks from a substation in a major city. I guess it's excellent because on these heatwaves, the system turns into a $100 clock-radio. When the heatwave subsides, the 3D psychedelic rainbow returns. I can't imagine if I was stuck with that bad power ugh. 

@mapman ....it does seem to verge on the edge of one, doesn’t it? ;)

I’m within .5 mi. of a major area hospital whose power consumption has to be phenomenal...so my power consumption must resemble a mosquito on the neck of Godzilla. ’Dirt level’, considering the MRIs’ and other SOTAstuff they’re running is either nil or off any conceivable chart....

That, and being in a small industrial clot, I’d assume that during the day...’blotto’.
At night, when most of my ’listening’ (serious or otherwise) is done is acceptable.

And, since I wear aids in my ears (unless ’headphoned’ and eq-corrected)....I can’t hear dog whistles or pin drop impacts either...

There’s a cell tower within 50 yards as well.....

So, class....’Yours uncoolly’ and those about here are so submerged in RFI, EMI, auto & truck ignition racket that concerns over the THD of line volts is likely the least of my concerns.....keeping the AC part of the HVAC up ’n running, Yes.

Not trying to be snarky ’bout it, y’all.... but ..🤷‍♂️
