Electric cars will ruin late night listening?

Bugsnest, I don’t think power conditioners help DC in your lines, they may but it didn’t help me.
 

I have a Running Springs Dmitri, Hayley and PI Audio Uberbuss and tried them all when I had a mechanical transformer hum on a Conrad Johnson amp. I had to send amp in for a replacement in 30 day period. The new amp had no hum so my problem may not have been DC in my line.

If you have DC in your line you can try a Van Alstine Humdinger DC line blocker $140. That was next move if new amp still had hum.

I did say mains powered generator, to avoid the air pollution and noise.

But I'm sure you're right.  There are fools on here that would think the fuel could affect the sound.

I agree with riley804, why worry? Gasoline cars still rule.Electric cars will not be in demand until there are places to plug them in.

Within a year there will be one in your garage cheaper than gas, a LOT cheaper !

It will be a long time until electric cars are less expensive than their gasoline/diesel counterparts. The cost of the raw materials for batteries, et al have gone up considerably. Operating costs will depend on uptake and the power grid energy sources. Full disclosure: I drive a plug in hybrid.
