As the title what is a grounding box.
Good question. I guess it depends on the box. Some seem to go to mains ground. Most don't.
Either way they seem to produce a reaction
They seem to be made differently. All say they improve sound quality.
My Coherent RTZ is a solid lump of metal
A grounding box is (usually, but not always) a passive box of mixed compounds that attaches to unused input and/or output sockets on the back of ones equipment. The concept is that it provides a low impedance route to 'ground' for the signal, as opposed to the mains.
However, there are a number of conceptual problems with the above aims. The two primary issues, as I see them are 1/ at some point in any hi-fi system the mains and signal grounds are tied together or the signal ground would be completely floating (this is true in the UK at least where every 13A wall socket has a link directly to ground (the earth pin). 2/ This parasitic ground box would have to have a lower impedance than that presented by the mains earth and this seems unlikely given the compact dimensions of all these accessories.
Bear in mind though that this a new type of accessory for the audio market (the only market such a thing exists for) and so 'what it is' and 'how it works' are not very well defined concepts.
Sounds like foo, I won't trouble myself any further, thank you gentlemen
I alway try to keep an open mind to these types of things. As much as I doubt they do anything more than just bunging a wire on to your gear to ground them, but the thing remains that they might. If I had one to try I would but not buying one to try
If one comes my way I will try it out - but I'm not yet at the point where I am actively seeking the loan of one and I'm nowhere near a place where I would consider buying one out of interest.
My set up sounds so good I don't think I could handle an improvement ;)
I have a Russ Andrews 'Power Purifier' grounding box with various additional modules which in addition to grounding also claims to to reject RFI and other stuff. Can't say I notice much/any difference.
Maybe I have very clean power and negligible RFI or maybe it is all foo.
I designed a mains filter which was copied and sold by a man with initials RA when I bought the components from him.
I think it was called 'the silencer' by him.
