Audiophile-grade ground rod?

@lowrider57
Thanks for the Fremer link which describes the solution to his major audio quality degradation after installing an external electrical generator for power outages. Learning a lot of useful info.

You want a low impedance path to ground and that isn’t easy to achieve. I’ve wondered how you can get around this. Multiple grounding rods should help.

Make sure that if using multiple rods, the scheme should be designed a single point ground - which IIRC the rods are connected in series vs parallel, otherwise the noise will be going from one rod back into another rod and a lightning strike may create an EMF impulse to fry your electronics.

Seems like a bit of resentment.  Fremer’s outside generator installation screwed up his sonics big time.  He had to spend the $ or uninstall the generator.

As always, it’s best to allocate/budget our limited $ wisely to try to get the best performance out of our audio chain.  Spending $ to lowering the noise floor beyond what we can hear and/or what 
our audio chain can reproduce is usually a bit foolish spending.  It is also usually best to address the weakest link in our audio chain.  Fremer’s Uber system is transparent enough and his trained hearing is good enough to hear minute changes/upgrades.
