What constitutes a grounding box?

[Macca]

Mike has made a very generous offer to demo his system but it would not surprise me if the cynics refused just in case they can hear a difference. The truth is that differences (improvements) are so easy to hear that it would mean a complete rethink for somebody who is sceptical.

.

I'd be happy to go to Mike's for a listen but he is several hundred miles away. I'm not cynical but I am sceptical and I don't accept that simple, sighted listening (by me or by anyone else) is enough to confirm that we have some sort of new science going on here (because what ever it is doing it has nothing to do with 'grounding' in electrical terms).

We're getting confused here, the Entreq grounds nothing, it has no mains earth link. The rtz is a different fish, apples and oranges.

Still has no mains earth link tho' ...
The RTZ, that is.

Okay, if the effect is immediate with yours you could also do a rudimentary blind test, maybe get the mrs to plug and unplug it while you listen without looking?

The results were immediate and obvious when each cable was plugged in

Correct me if I’m wrong Mike but I believe Tony claims the RTZ box works in a different way to the others on the market as indicated in your thread on TAS...

There is no rocket science here, just grounding principles taken to a particularly conclusion which produces the desired results

Vertex Aq, Entreq and Nordost all have products which claim do produce a similar condition

However on this occasion measurements will tell you what you need to know with these products.

Struggle with the tech and this grounding seems akin to magic.
Tony spent a few years before he was ready to let a grounding box into the wild having looked at the competition.
The advantage of his is the amount of connections that can be made without spending £1000s on more boxes.
Seems logical to have *one* grounding box too

Stab at being technical
All kit has an operating voltage of zero to x.
Kit doesn't seem to get to zero or even moves around so is not operating right.
This seems to have a knock on to sound quality
The grounding works on the box it is connected to by taking the voltage that should be zero to zero.
All connections are to RCA and other sockets via the outer (ground ?)
No earth connections. These are different

With devices such as this sighted listening is not good enough. Needs to be tested when you don't know whether it is in the system or not. Don't know of you have ever tried any blind comparisons but it can be much harder to spot the difference when you don't have that prior knowledge.

Due to laziness I prefer to go up. Although I can go both ways

Advantages of going up : You hear the additional
Going down : Not always easy to work out what has diminished or been lost.

I'm convinced the sound is better with the RTZ

A big part of what constitutes a grounding box are the cables.

Yes they make a difference.

Visit from Tony, The Doctor yesterday with new, burned in 6D cables to replace the 4D I started with on the RTZ

I chose to upgrade having heard the difference before.

Test
Tony changed one 4D for one 6D.
Big step up heard in the first few bars. Like the volume has been clicked up a couple of notches.
Such detail
The sustain goes on and on.

Swapping more cables sound even better

Whatever grounding box you choose audition the cables

Not surprisingly Tony's (Coherent) take on grounding boxes is different to what the competition have.
My guess is he has it sorted.

I have to admire Mike's tenacity posting on this thread.
