Maybe this has already been posted here somewhere, but I stumbled across this little jewel as I was perusing the source of all knowledge:
Skeptic James Randi, through his foundation, has offered a prize of $1 million to anyone who can demonstrate that $7,250 audio cables "are any better than ordinary (and also overpriced) Monster Cables".[15] To date, no one has claimed the prize.
You can find that jewel at:

I like nice cables, but not insane cables. Would be interested in others' responses to this.
Actually, maybe the site to post this on is Stereophile.
