Best place to live for good quality power

@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 ..🤷‍♂️

first define quality.

The vast majority of issues we ensure are noise related.

Noise comes nto from the service provider but from equipment operating on the grid, often right in your neighborhood. I'm talking to you air conditioner, or the millions of capacitor input power supplies not-so-gently clippng the opts off waves and delivering back emf into the power network.

So its us.  And its a question of time - what hour? What day? what season?

Get a good filter. And honestly, not all equipment does an equally good job of rejecting noise.

But this is exactly my question. Some people said living away from noise-polluting sources does not guarantee a good sound - such as rural areas with terrible physical infrastructure. So I assumed majority was noise-related, but may not be true. If the power from the source is very poor, thats a problem.

First don't obsess. Second, I thought I was clear the problem is not the source. For a bunch of technical reasons I won't get into there is really no such thing as a poor source. Just pollution between the source and you. Therefore the answer is a filter. When I say filter it could be a passive filter or is one person suggested a regenerator — which is an awesome filter but carries with it lots of other problems like high source impedance.

+1. You can do something about noisy power. It is also relatively cheap and simple to improve compared to others.

How quiet your listening room is really important. If you can drop your listening room to the 20 - 30db range you give your system an enormous advantage.

Of course, you can do something about noise pollution… Moving to the country can greatly reduce this. Or spend a lot of money insulting you room and or house. But that will not reduce physical vibration which improves sound quality from components… from cars and trucks rolling by, airplanes and other urban stuff.

Then there is room geometry and acoustics. Huge impact.

There are so many variables to control. Powers just one.
