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.

I had to use paper money on my Gallo Ref 3s because the coins kept rolling off.
I found change not to work as good as 10K dollar bills in each corner.Of course you may need to go to a bank to get them,cheers,Bob
I believe that Sam Tellig once had a few words to say about this (positive I think). I would recommend it only if you are tempted to spend $100 for some rocks in a bottle.
