Electrical Panel Grounding

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.

Eric - thanks fro the input.

Jea - I read the article, and there is a bit fro me to learn. Thanks for your trouble to forward the link.

I should have mentioned you only need to read about the first 36 to 38 pages of the white paper.

I also should have asked you, in my last post, what country do you live in?  Earth ground is earth ground the world round but how it is accomplished/done/required varies. My comments are for the USA.

Here is a video on the subject of the use of an Auxiliary Grounding Electrode. It really serves no purpose and can cause damage to electronic equipment if used in the event of a nearby lightning storm.

Jea - that youtube is exactly what I needed to know. This forum is amazingly helpful because a handful of people, like you, care enough to share.

I live in Denver with my wife, Lori. My system consists of a custom built pre-amp using two B29 tubes and two small front end Mullards. It is with transformer or OTL switchable circuitry, and switchable capacitance so I can tune to the source.
CD's need less and Vinyl more.

The amps are custom made with two 6C33C tubes per monoblock, 4 Mullards for the ancillary functions and a fairly massive output transformer. Class A/B with a solid 60W per side and 5 separate transformers for the various required voltages.

These amps are plenty to power my Soundlab U-2s. I prefer the U-2s 6' x 3' size over its larger brethren. These have been modified is several ways not easy to explain.

All running Audioquest cables, mostly silver over copper. I know that is way more than you asked, but I somehow thought you might find it interesting. One day I do a post on the pictures/system page, as the room is covered with my own acoustic diffusion and absorption panels which were sized and located by ear and trial and error. If you ever want to build your own, I do have some useful tips that will save you from learning the hard way like I did. And they work better than any of the stuff I tried that was made commercially at about 1/10th the cost.
