    It's a box with a light in it. LOL

    I wouldn't know what it actually does.

    IMO, probably very little in real world terms. But if it's expensive, then it must 'seem' to do something.

    I would give it a go I suppose, always open to stuff. Some people like R.A.

    If someone here of a more technical mind would like to attempt to explain, that would be good.

    Yes. It sounds good.

    Still remain very skeptical though.

    I have a considerable amount of experience with RA.

    In the 90s when I was building my distribution boards, one 9 and one 11 way, they were from varnished wood, and I decided to copy a BBC design in which mains inlets to amplifiers had 0.01uF caps across all three of the mains connections, in delta form.

    I increased the values to 0.1uF and contacted RA, and without realising his stance, discussed what I was doing, and IMO he took all of this and used it to further his business.

    He introduced several mains filters, one of which is a plug in wall wart called "The Silencer", and out of interest I bought one in about'02 to test it.

    With three switches, one in series with each leg I measured any change in noise levels on the mains, and it was undetectable, but my own filter was in place at the time. It seems to be composed of what I used, three caps, but with the introduction of a voltage dependant resistor, which he revealed in a subsequent discussion.

    Other products I do not know about, but he has made a lot of money and is very good at marketing.
    When I told him of my measurements he discontinued sending me his literature.

    Could this be a bit of 70's Peter Belt 'technology'...? OK so his headphones were bloody good but I think it all went a bit 'Icke' later on.

    I'm a bit surprised it's not in a blue box.

    Tried most of Ra range, one of the few makes I now universally dislike. I’ve come across nothing else that kills the musical message so effectively.
    Peter belt was a man out of time, most stuff he espoused is in realm of quantum mechanics, and the nano universe. Most bonkers but fun finding out.
