Audiophile-grade ground rod?

@jea48
2 rods tied to the panel’s ground buss bar and 6’ apart, correct?

What’s the advantage of using 2 rods on a simple residential service panel?
(I have two ground rods due to having a subpanel).

And watch Fremer's related video. Very interesting.

@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.
