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.
