thanks soundhound.

I was wondering what vibration had to do with solid state electronics. I just could not see where it would matter. The only thing that I could come up with, ( and this is a long shot I assume) is that with a cd player, maybe ( again this is a long shot )maybe if you had enough vibration you might mess with the path of the laser, maybe. I could see how it might screw with a turntable. I don't have any records, never have. I guess that is mostly a function of my age ( only 26 ) so.... again thanks for the input soundhound. I am curious to see what others have to say.
