Don't start with the impossible. Attempting to 'isolate' vibration nearly as dramatic as attempting to paint the sky red. The term 'vibration isolation' is an oxymoron.
Sure you can put an air-bladder, tennis balls, sand, etc. under a component to isolate it to one extent or another from floor-borne vibrations. But now how do you address the air-borne and internally generated (electrical and mechanical) vibrations captured by your components?
And the big question is which of the 3 types (air-, floor-, or internally-generated) of vibration induce the most sonic harm?
If you answer that one incorrectly then it really doesn't matter what you do.
-IMO
