    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.

    The RTZ, that is.

    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.
