Electrical Panel Grounding

Wguts, none of this is necessary nor will it improve anything.

What matters is that it all be referenced to a single point, where the neutral is bonded to it. Putting in a single, or 20 ground rods won’t help this at all.  Follow the NEC, and local codes which may now require 2 rods.

I’d focus on your room acoustics. :)

The point of the ground is to act as an earth safety, which it can only do well if bonded to the neutral at 1 location.

Now if you want to run isolated grounds from the panel, that's fine.

Thanks Eric:

As an audiophile, we have had success in the past with using a ground field (multiple ground rods). My associates include a satellite engineer who made the original suggestion. I believe I have a audiophile grade system. I am using Sounlab U-2 electrostatics driven by 6C33C power tubes.

Since you brought up room treatments, I work on this every weekend. One question you may know the answer to is regarding 2" square wood block diffusion panels. While using longer pieces of 4" and 5" I understand this will increase the octaves covered over 1", 2" & 3". But what discernible sound effect would this have? it sounds to me as is there is some additional blurring in the mid-range.My focus is to tame some high frequency hardness.

High frequency hardness can be caused by local RF affecting signal via unshielded ICs and speaker cable (think Kimber, Nordost).

wgutz,

A mix of diffusion and absorption is always a good thing!

High frequency hardness is a funny thing. While a lot of people focus on 1st  and 2nd reflections, this can also be treated by generally adding absorption in the room. In other words, some of the problems are due to direct reflections, but some are just doe to how slowly or quickly it takes signals to decay.

You can experiment cheaply with throw rugs/blankets and putting other soft, absorbent materials on the walls. If that takes you where you want to go, then you are going in the right direction.  Also, don't neglect the ceiling!

You may also experiment with toeing speakers outwards so you are not in the direct line of fire of the tweeter.
