    So you have multiple grounding rods?

    no, only one.....but it's in the ground maybe 4 feet from my Equi=tech panel. I live in a 'rain forest' climate with what I've been told are ideal soil conditions (it was tested at the time). i do not recall the exact info on my ground rod; only that in desert or eastern US areas the soil conditions are more challenging to overcome.

    My electrician was just here. The panel installation is straightforward.

    We talked about the grounding. Currently I have a copper wire running to my main water line and a second run to a zinc rod in the ground. There is a 2nd rod which attaches to the first rod, 6 feet away, which is required by code.

    It sounds like I want to run a grounding strap from the panel to the rod outside and figure out what rod to use.

    Once again, the connection to Planet Earth has nothing to do with day-to-day AC power quality. It is there for safety during thunderstorms and other high voltage problem events. Do whatever makes the electrician and the inspector happy.

    What are you basing you comments on?

    Sorry it it not true in reality, where power transformers can suffer from leakage to the secondary and equipment is not designed according to ideal rules. We are debating consumer high end equipment, not military specified and certified equipment. And noise is not just hum!

    It is why, for example, some instrumentation research laboratories and facilities specify extremely low resistance ground connections - we do not want to have problems with what your neighbor does in his section.

    Every good engineering book and paper on the subject of AC power.

    With AC power noise, interference, leakage, lost Neutral and Ground currents have no interest in Planet Earth. They are only interested in getting back to their source which is the power company transformer.

    I respectfully disagree, but I would be curious to hear other people's takes on this.

    I am currently considering a 90A Torus wall mount unit versus the same 90A Torus standalone unit (Torus AVR 90, which has a 90 amp balanced input unit). So headroom is the same either way. The stand alone unit takes a 50A, 250V twist lock balanced plug. If EVERYTHING in the audio system plugs into the same power unit, I have a hard time seeing why a wall mount unit would be better than the same version of a standalone unit and the wall mount unit may actually be worse.

    With a standalone unit all audio equipment plugs directly into the back of the power unit. Therefore, the only external influence is your power cords.

    Whereas with a wall mount unit, the audio equipment plugs into a number of branch circuit receptacles that are in-turn wired back to the wall mount unit. So with the wall mount unit, you introduce more variables with wiring from the wall mount unit to your receptacles as well as the receptacles themselves. Also, EMI, RFI, and compatibility influence the wiring over these distances.

    I can see where a wall mount unit can be useful when you need receptacles in various locations, particularly when you can place a receptacle at a remote media server in another room (so you can ensure that your remotely located devices share the same power, neutral, and ground as the audio devices in your listening room)(otherwise you are introducing different grounds and neutrals into your audio system through the interconnections to these devices.)

    While it isn’t always the case, in the case of power I do think size matters.

    I just had my 10WQ installed today. It took 4 adult males to lift the unit up so that it could be attached to the wall. Thus, my guess is that the transformer in this unit is going to be able to accomplish more than the transformer in the shelf unit.

    Just speculation since I not compared them in my system.

    I am not familiar with the Equi-Tech units. Regarding the Torus units, I believe the transformers are the same for the wall mount vs standalone units. For the 90A units, the weights are similar 233 lbs vs. 200 lbs which makes sense because of the extra breakers, case work, etc.
