No where we stand is just like Glupson said in the first post here and audionuttoo reaffirmed.
"Sound is, in the simplest term, a vibration. No vibration, no sound."
Where we disagree with you Geoff is when you say "vibrations should be killed" or however you say that phrase. What is it "a good vibration is a dead vibration" or something like that.
Vibrations are very important because it is a word that can be used in the out of tune sense as well as the in-tune sense.
