Steve, Thanks! That is very useful information for me.
Last evening, I was getting readings as low as 54mV. It was the same this morning until businesses started up again. This is proof that listening at night does sound better.
This is exactly what I also know to be true, without a meter, I hear obvious improvements here beginning late evening, and during other more randomly occurring time periods. My feeling is that air conditioners are quite big culprits. Not just our own here. When I got my Hydra things improved some. But, I’m still going to keep on at attempts to further clean up my power supply.
