    Default What constitutes a grounding box?

    I'm always on the lookout for things which may improve my listening experience. I've seen these advertised and the idea looks sound, but not the price. So, just what constitutes a grounding box? It could be argued that careful attention in cabling management could mitigate the need for such a device, but for fun it could make for a DIY project. Any thoughts, suggestions, lads?

    Just take a large wooden cigar box, fit it with a gold-plated binding post and fill it full of coal - then tell your friends it cost 1,000. That last bit is important - your friends won't notice any improvement unless they know the price.
    Have you listened to this month's choice in the Album Club?

    There is no agreement as to what constitutes a grounding box as the concept has only recently been ‘invented’ and only by the audio accessory fraternity. In the UK every mains socket already has a very effective grounding pin, called the earth.

    Here's some measurements done on one of the Entreq offerings. Quick summary: Performance depends on how long a wire you use to connect the system to the box. Longer wire injects more noise and distortion, short wire adds less. Probably none of it is audible. So in effect it does absolutely nothing - which is what you'd expect. However for the man who already has everything else it's a bit of fun I suppose...

    I've noticed that people who own these find the benefit increases the more things they connect to it (and the more 'grounding' boxes they have). The more cables you attach to it the bigger an antennae you are creating so more RFI will be picked up. Possibly to the point of audibility. So it seems possible that it could affect the sound although technically it's a degradation. But of course it's all subjective, a degraded signal can sound 'better' to some.

    It's a good site if you want independent technical info without having to wade through all the frizzley stuff.

    Firstly I cannot see how the addition of a box, whether conductive, (Cast alloy for eg.), or non conductive can do anything unless the conductive box is earthed. In this case it will act as a screen to e-mag and e-stat fields.

    But then, why a box, unless it encloses a piece of equipment to thoroughly screen it. Obviously a piece of wire will become an effective aerial if not earthed, so one has to ask WTF is this meant to do?

    The results from the link speak for themselves - complete and utter BS IMO.

    We all must go out and buy a dozen or so.
