Audiophile-grade ground rod?

@jea48, thanks for the detailed explanation. I didn’t consider the amount of resistance would change with the grounding rod(s) + cable added.

If you watched the Michael Fremer video, he went all-in with his grounding scheme.

@lowrider57

Yes, I did watch the video. It was pretty interesting to watch.

I don’t think I’ve ever seen Cadwelds (Trade Name) used in residential for connecting the ground wire to the ground rod. That welded connection is forever.

One thing for sure Fremer was ready for a new electrical service. Did he say how old the house was?

There are some DOD research papers on the web somewhere, have not read them for years. Then there is the Ma Bell triple point grounding system. Even water table management is going to be required. Then you start getting into a rub in that the earth can become a source of noise in your system. This where a local knowledge of the geology of the area needs to be taken into account. Best bet is to find out what Ma Bell and Sprint did in your local area and work from there. Survey says...

Best bet is plug your stereo into the wall and enjoy the music.
