I saw david blaine bite a quarter in half. I also saw him have a lady write her name on a playing card and the card was later found in an unopened bottle of beer. I was amazed! I know these things could not have happened, but that didn't make them any less enjoyable to watch. About a year ago i added a new amp and a voltage regulator to my system. I was very happy with the upgrade, hearing details (imagining details?) that i had not heard before. There are those that say there are no differences to be heard. That didn't detract from my enjoying my system more. I can put on a cd, close my eyes and i'd SWEAR holly cole was right in front of me! I KNOW she's not in the room, but i suspend belief with the help of my equipment. Be it real or imagined, the upgrade made it more realistic.
There are those that swear they hear improvement by putting four quarters on top of their speakers. I DON'T hear it, but if they think that makes the system sound better, more power to 'em. Who am i to say otherwise? This hobby of ours is all about creating illusions. If a new amp or power cable (speaker wires anyone?) help persuade me (or you) that for just one moment we are in middle earth or leo kottke is in my living room, who is to say they don't? Maybe the pipe really DOES bend in the water.
