Spare change on a speaker cabinet

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.

totem beaks are sold to do the same thing....only they are more than 37 cents.

You have to use special Audiophile pennies (called AuraPennies), which are actually made in China - though they ARE designed in the U.S. Depending on the room size, you need between 6 and 12 pairs.

They list for $34.56 per pair (regular), while the Cryo treated go for $45.67, but can be found on Ebay for less. Be careful though - these things look EXACTLY like regular pennies, so you could be burned by unscrupulous Ebay sellers. I'm also told they can lose their effectiveness if shipped improperly. Better to pay the premium at your local AuraPenny dealer, since they will stand behind their product.

There are also silver AuraQuarters for quite a bit more $$$ money. I'm told they can be too bright sounding with SS equipment but may be suitable for tube/horn systems - though balancing them on the horns is best left to an expert.

Also, keep in mind that they require a significant "burn-in" period before your wife will be convinced that the money was well spent.

"John, I can't tell if you are kidding or serious..."

You really can't tell if he is kidding? Oh, my....
