I dug around Shunyata site and did not find where Calin talks about grounding with a bar of copper and 16 awg wire. Can you point it out. I have tried a few times in the past to make this type of install work. I have a 1/2" thick OFC copper bar I drilled and tapped to accept wires. I have used 10 awg bare copper, 14 awg bare copper, 20 awg dead soft silver wire, 20 awg dead soft silver wrapped in cotton with a mylar shield that is grounded on the bar end only. I never heard a thing with any configuration. I have bonded the bar to the ground system at my house with a dedicated bare copper #4 dropped 4 feet a ufer ground bonding my entire electrical system that reads about 4 ohms. Still heard nothing. I have taken the #4 and split bolted all the component ground wires I attached to the ground stud and still heard nothing.

My point?
Are you saying that EMI current can be drained, diverted, to the Earth? Where’s the circuit? Through the Earth, to where? It has to return to the source doesn’t it?
Henry Ott, Myths:
6. An earth ground is unidirectional, with current only flowing into the ground. False, because current must flow in loops, any current that flows into the ground must also flow out of the ground somewhere else
Somewhere else? Back to the source?...
Why would the EMI current travel through the ufer ground, (concrete-encased electrode), to the earth to get back to the source when it can travel through the #4CU conductor, (Grounding Electrode Conductor), that connects the ufer ground to the Grounded Conductor in the service equipment panel?

After watching the Gabriel interview video I posted above, here is my understanding of how the Shunyata Altaira Ground System works,
Each of the two Shunyata ground filter boxes has 7 grounding posts. 1 thru 6 are for audio equipment connections. The 7th ground post, identified CGC, is for connecting the common clean ground bus of one filter box to another Shunyata ground box. The identified ground post is also used to connect the CGC ground post to a reference ground of the building AC power system. (Therein the EGC contact on a wall outlet or an insulated IG conductor installed back to the System Ground of the electrical service. (The final point of connection being the electrical service Grounded Conductor.)
Each of the 6 grounding posts for the audio equipment are connected to individual EMI noise filters. (Therein each grounding post has its own filter. The other end of each filter is connected to a common ground bus. Supposedly there will not be any EMI on the (filtered) clean ground bus.
All of the audio equipment (grounds) are connected together by the clean ground bus... The identified CGC ground post is also connected to the clean ground bus.
The EMI filtering takes place in the Shunyata ground filter system box... Mother Earth is not involved.
