Spare change on a speaker cabinet


Does anyone know of a tweak where you put a certain amount of spare change on the corner of one of your speaker cabinets (or both) to improve the soundstage? Sounds crazy but I heard it once and it did seem to work. I heard it in a store in NC.

Thanks.

Oh for goodness sakes. You're not serious, are you? Sit back, think about it for a while, and see if you don't feel silly for asking that question....

Don't you think other things within that store could have caused this or changed things more than spare change on a speaker? perhaps a sales person standing within the room?

would using different currency, say a Yen, Pence tailor it to the Japanese or British sound?
I would think it would only work if it was the change left over from the purchase of Brilliant Pebbles.
