Rotarius,
Fair warning! Nasty wars have already been fought in this forum about the efficacy of the devises which are purported to drain vibrations from audio equipment. Been there, done that. When it was all over there was no agreement about anything, just a lot of PO'd folks. :-)
Oh crap! We don't need more PO'd folks. Our hobby is all about perception anyway. Just thought some of you might be interested in how it's done in the *real* world :)
