use various footers under isolation transformer, however, my issue was using them under transformers in an electronic component chassis. My apologies if I didn't make myself clear about that.
In an electronic component with active circuit, motion is not very good. With tube gear, that would be rather obvious, but few realize even solid state gear sounds better if vibration is kept away from the circuitry.
Very early on, when Sorbothane first came out, I remember applying small bits, about a 1/16 inch square, to the tops of the TO-92 transistors in a PS IV preamp. The change in sound was dramatic: the characteristic "bright" PS sound became very warm and rich, and yet the PS had an external power supply housing the transformer.
Pondering over why this would be so lead me to dissecting transistors, and it was an education to do so. TO-3 types have tiny little wires jumping the leads to the actual transistor element, roughly a 1/4 inch square, and it is set in a hollow space, although early types are curiously fluid filled (heat transfer?). The fact that you have tiny wires attached to a basically a pure silicon element sort of makes every transistor a modified crystal oscillator to a certain extent.
Again, I would reiterate and say that it is best to keep any source of vibration as close to the source as possible. Diffusing the energy into other components is generally not beneficial for good sound, as that energy is changed in frequency and amplitude, but still present. If you are extremely careful, it is possible to transmute that energy into something outside of the audible bandwidth where it may be relatively benign, which seems to be the goal of most designers. Otherwise, you get an accentuation of the resonant frequency of the device in question.
