    You can't do that - once the novelty of the box's original contents has worn off it (the box) becomes the most played with thing for the kiddies.
    Spend a fortune on the contents, and you should have just given them a pile of boxes to play with

    "it's a load of bollocks", some might say. In fact I know people who probably would express a view to that effect. As for me, I'm far too polite to pour scorn on anything .

    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?

    .

    If you read through all the tests they conclude that it's an antennae, there's a wire that runs right around the inside of the box. Some suggest that increasing RFI noise in the system can give the perception that the 'soundstage' has expanded. Interestingly this is the positive effect many users of such devices say they hear. Assuming this is actually what is happening (which is still a big assumption) you could just plug in a very long wire and leave it unconnected to anything at the other end and get the same effect, the box is completely superfluous.

    So maybe the way it works is sort of similar to adding a dither signal, if all it does is pick up and inject noise?

    I think this quote sums it up nicely;

    So that is it for now. Bottom line is that the device seemingly does nothing. The only measureable effect is the wire that goes to it. That wire acts like an unterminated antenna so picks up whatever noise there is in the vicinity and injects it into the signal path. Depending on what noise there is, and how the equipment behaves, there may be little to a lot of noise injected.

    That was one theory advanced, although the counter to that is that the injected noise is at too low a level to make any audible difference. That seems to be a grey area though. Even if it was the case that it is audible there's still no need to buy the box to get the effect to work.

    The effectiveness of the box of shite may ultimately depend on how “wet” the shite is, for effective conductance. So it might seem one would have to adjust ones shite schedule, as well as consistency for it to work well.

    Not necessarily. Quite possibly, the drier the better in fact, as in principle, it could rely on diodic action within the crystaline structure of the dried turd.

    Well, that could be Geoff! Guess there are quite a few smelly ways to look at this shitty situation!

    Does that help the bottom end?
