I visited the home of a high end distributor who has bowls of water strategically filled and placed around his room. I can't recall what his claim was, but when he was out of the room, I couldn't resist pouring a little water from one bowl into another. He didn't notice.
I once went to buy speakers and while I was listening the sales person made me remove my digital watch and place it in another room. He said it's digital signal somehow changes the bass and imaging of a stereo. I did buy the speakers.
lol...damn my feeble brain. Why didn't I think of rebranding and selling it. You guys are brilliant...this is why I'm just a newbie at this.
