Mains power quality worldwide.


Is there anyone who has sampled power quality in different regions? Is there say a difference in quality between 110V and 240V. My reason for asking is that I see discussions about relatively expensive mains filtering and running dedicated power lines directly from the consumer unit.
Where I live in Cornwall UK it’s 240V 50~ and where I used to live in the Nottingham area. Without any filtering or dedicated power feed, the power is pretty clean, except for a second when the boiler or air con’ kicks in. I can get it really clean with quite modestly priced filtering https://www.amazon.co.uk/gp/product/B00UB0G4DQ/
Turning on other equipment seems to have little effect apart from their initial start up, with the exception of the air con’. If the scope (a friends equipment) is connected to the DC end of the amplifier PS there is very little at all. So am I just very lucky?

France is largely nuclear, the sound quality radiates. Germany has gone wind power, so when it works (and if you can afford it) you can look forward to a lot of air. Here in the US the east coast is coal, the sound is dark and grainy. On the west coast California you can no longer listen except during certain hours, they need the water for the snail darters and the electricity for AC and to start forest fires. Up here in Washington state where I live we have the best power, all hydro, which is why my system has such a beautiful liquid character.

I'm sorry. Was this meant to be a serious question? Someone moved their whole entire system from one country to another auditioning the power? Really?

There are differences of course but for our purposes they are all the same: crap. None is any good. All benefit from an endless array of conditioners, power cords, and Krissy magic.

Well, I would consider relocating for better power for audio is another tweak for audiophiles.

Yes it was a serious question. After reading so much about it here and elsewhere, I just wanted a clue as to if there is any noticeable differences.
Clearly your claim they are all crap isn't a fact, as my experience here says otherwise. I was merely interested if some others had decent power or if I was just lucky.
