Audiophile-grade ground rod?


Anyone know of a high quality (purity) copper home grounding rod?

Replacing my old rusty one will be significant, but wondering if there are brands that are higher quality than others.
thanks

Audiophile grade ground rod is easy. Wait till you go looking for audiophile grade ground to drive it into!
Couldn't you just use a copper pipe and save a few hundred dollars?

If this is a DIY project how do you find where to connect the ground rod to the electrical wiring in the house?
