I have measured with a meter a reduction in noise in a panel when its grounded properly. I have eliminated certain noise.
I have no doubt in what you say. But show me the circuit. Here is the circuit as I see it.
The EGC, IF used, >>> to the service equipment grounded conductor >>> to the neutral of the split phase secondary winding of the power transformer. There, some, of the noise energy is dissipated in the winding in the form of heat.
Mother Earth is not involved.... Show me the circuit if you think it is. Please provide any credible proof from someone like Henry Ott, as an example, who says noise can be "shunted", diverted, to mother earth. Show me the circuit if you think it is. You said, Quote: "Read the Sores books. Read the Morrison books." .... How about a quote, a White Paper, of Morrison’s that will backup your thinking.
Those in authority need to stop telling audiophiles noise on a circuit ground can be shunted, diverted, to earth. I still read current posts where audiophiles are driving a rod outside their audio room using it to replace the branch circuit EGC. Dangerous as Hell... And in the case of a bolted ground fault it will never trip the circuit breaker in the panel. Never...Works great for hunting fish worms though.
Finally this:
If you really want to scratch your head, prove to an engineer a ground box like Entreq or Altaira reduce noise.
I know nothing about the Entreq...
What I know about the Shunyata ALTRAIRA Ground System I learned from watching the video I posted above. What Gabriel has built, and his explanation of how it works, makes sense to me. He uses individual filters that are connected, to each ground post on the back of the box that are then connected to a common ground conductor. So all the filtered grounding posts are connected together.
He has two boxes. One for the Chassis ground and one the signal circuit ground. NOTE no where in the video does he promote floating, disconnecting, the EGC from any audio equipment that uses it. If fact, as I remember from watching the video, He says, and rightly so, the electrical service connection to mother earth is for lightning protection. Not for, shunting, diverting, noise to earth...
He didn’t fully explain, unless I missed it, how he treats the chassis of Class II double insulated audio equipment where an EGC is not used. That equipment is different... That equipment the Signal ground and DC B -, is connected directly to the chassis. One mistake I caught was him saying tube equipment designers connect the signal ground and DC B - directly to the chassis. That’s not true. Some might, but not all.
What I did find interesting, if true, some equipment noise the rectifier(s) make in the DC power supply(s) circuit designers dump it onto the chassis. Maybe Gabriel could show them how to install a filter between the signal ground, DC B - , and chassis. That would solve a lot problems.
