Hi Xanthe, howzit all goin’ these days ??
Why I’m not puzzling over so much the ground side is its either connected or not & in the case of DIN & RCA there is nothing other than -ve (ground) & a few cm of wire & open PCB tracks
If it is only on -ve (ground) it can/will act as an antenna.
It might be an RF stub, as I understand their cable ARAY system is, so I would like to know more.
My more puzzling thoughts are what do the other connection forms connect to, are Chord implying this is a one application system that works on all connection types ?? if so even more unbelievable.
But time is too short, better things to fry at the moment, until I read a credible engineering explanation, I’m not buying. .
Maybe Chord can use a few drops of their rarefied arctic viper oil to ease off the hinges in the secrets box.
Maybe ask them direct what and roughly how they work; and take marketing with a grain of salt.
People may remember that years back, Naim got done by trading standards for some bollocks text cooked up by their marketing company for PowerLines. But it doesn’t make PowerLines nonsense. Naim have been quite upfront about the goals of the PL. I’d reserve judgement against the product and disregard the marketing claims. Start with just, are they better, worse, the same? Work back from there and ignore the marketing claims for now.
Reverse engineer one if you’re curious, or better: ask Chord Co (an actual engineer) and report back.
They work in a similar manner to the Naim floating/non floating switch. (Which provides a single connection of the Naim 0 volt network to ground).
Chords groundArray and the Scandinavian system that use large wooden boxes full of stuff, work in the same way, but act on localised circuits. They effectively perform the same function as the ground (soil/clay that surrounds our houses).
Has anybody who has trialled the Chord GroundArray’s compared the results with the Naim floating ground switch on and off.
Nice try Fatcat, but a little short on detail.
And the Naim signal ground switch is something else entirely.
Yep, there sure is a lot of copy and pasting going on…
I’m trying to help you with the concept, not the detail.
Let’s try again. 
The Naim signal ground switch allows the signal ground to be connected to the actual ground. (soil/clay that surrounds our houses).
The entreq ground box is a virtual real ground (equivalent to soil/clay)
We use different layers of metals mixed with minerals to create a galvanic point that acts like a concentrated piece of Earth.
I assume the chord groundArray works in the same manner.
So when you use one of these devices, you are connecting a localised (in a DAC, streamer etc) ground to a virtual concentrated piece of earth.
Thanks Fatcat, but with all due respect as an electrical engineer, together with radio, radar & satellite coms, the ‘concept’ is not what myself & a few others are looking for.
That aside, the Naim ground switch is specifically to allow the user to switch off the streamer units
-ve signal to ground path when the system has another source component with a fixed signal ground such as a Naim CD player.
Mike. I think you’re splitting some very fine hairs there.
“The Naim signal ground switch allows the signal ground to be connected to the actual ground”.
I use an ndac, which is the only piece of equipment I use that has the facility to be connected to ground. The switch is used to connect the signal ground to the actual ground.
Reading your posts I got the impression you weren’t aware of the concept. Without the concept you can’t drill down into the detail.
The concept might be bollox or might be brilliant. I don’t know.
Nobody knows.
I know. It’s bollocks.
The Naim switchable signal ground is ‘bollocks’?
I wouldn’t know, afaik I don’t have one.
As for the GA, I’m still evaluating as I really don’t get much time for, um, serious listening (gawd, that it should come to this)…I wish my lovely wife would go out more in my days off!
I believe you know what I was referring too. The naim ground serves a practical purpose. A silver dildo serves only to extract £500 yes half a grand from men.
Given what a dildo is supposed to represent, I’m surprised anybody could describe the GroundArray as a dildo. 
I’ve got one from the dealer to try and found the same as Geko ie loses integrity and emphasises top end to sound too etched. Better without. That was the one tried with 252.
Does the GA win the award for the most despised bit of kit of 2021 yet?
Interesting. I didn’t find the top end ‘etched’ but maybe I’m used to that with the 805 diamond tweeter!
No not at all, I’m just being inquisitive trying to understand something that appears to have no logic.
I’m an electrical engineer, I know the laws & principles, I used to lecture on the subject, but maybe I just don’t understand concepts (whatever they are)
Subject closed from my side, that is until someone explains in engineering terms what’s inside & explains what & how.
Mike
The splitting hairs comment only applied to Naim switch controversy.
There is no hair splitting hairs on that one, my description is perfectly correct.
