Clean ground

First no, none of them require earth ground. They have the third ground but not a one of them requires it. In fact they will as you already seem to understand only be noisier if connected to another wire going to ground.  

Matter of fact, Mike Smith of Fidelium was just at my place recently for Chuxpona and saying the exact same thing. In fact he carries around a cheater plug to prove his point. So there.  

Probably you will reject this correct and useful advice. This always happens. So what you do then is establish your own earth ground with a ground rod, run a wire up into the room, connect it to a grounding box (fancy term for a bus bar) and ground your gear into that.   

We now return you to our regularly scheduled yada yada.

Hi Pauly,

The ground is there for safety reasons, but are not part of the audio or power circuit until a fault occurs.  When a fault occurs which allows voltage to flow through the chasis the safety ground (that pesky middle pin) conducts 15 or 20 A blowing the breaker before anyone can be shocked.

So, no the circuits does not require ground but safety does.

The best ideas I have seen is to use a high power inductor on the ground. Something that can take 15 Amps.  This will allow you to meet code requirements and also keep the noise out of your system.  I believe some expensive power conditioners now do this.

If you are completely off the grid though, with no grounds like cable TV or anything else connecting you you can create your own ground which should be noise free.

Best

Thank you for you response but ;

1.) I have active cables that do not work if not connected to ground.

2.) I need my ground not to have an elevated AC resistance as my cables dumps  EFI and EMI onto ground. An inductor would be as bad as no ground for this particular function.

Hence me asking how to establish a separate ground.

@Pauly- you sound like you know your way around a soldering iron, so I don’t want to patronize you in this response, but are you talking about a clean dedicated ground that is connected to the main ground or an isolated ground? I have the former- a run of 4 gauge directly up to my room at the time I had the wiring done. It is tied to the house ufer, as I think is required by Code. @Jea48 is your man on Code-related issues assuming those apply where you are.
Let’s see if the link will work to an image. If not I will delete. The photo is there and shows the buss bar and the black 4 gauge feeding it. Sorry it is out of focus in that part of the photo but it was the only close up I had that included it that I could find quickly online.
