Lately I've seen a company selling two 12' speaker cables for US$7250 (Pear Cables) and another selling two 25' bits of copper wire (basically) for $43,000! Is there any way to test whether these things actually make anything sound better? It reeks of a scam - though not as much as the makers of an "intelligent chip" which uses "quantum effects" to make your CDs permanently more "optically transparent". Using - you know - those quantum thingies? Maybe they use fur from Schrodinger's cat. Google "brilliant pebbles" for more audio myths. I'd like to see the Mythbusters take a crack at any of the hifi or audio claims.
