just my 2 cents on whether vibration control works; in some cases an unreserved yes.
I had a pair of silver/copper pro silway IIs that had some nice bass control and openness qualities when used with my CDP but they also had a horrific tiring glare. No getting around it. They sucked in that role to the point of being unlistenable.
I had some mixed metal chrome/sorbathane feet deals (about 1.5 in dia at the base) under my tube pre to help control vibration impacts to the tubes. I'm not sure if they really help out all that much under the pre but when i put them under the CDP the glare from the Pro Silways was gone and the whole shebang tightened up top to bottom. Points up vrs point down...no significant change that i could tell. would other vibration controls work better...can't say and don't really have time to try these days. However, controlling the vibration at the source at the macro level helped unquestionably. On a detail tweak side of things it did seem that the sound was a tad better with the cages off my amps than with them on but the arrival of toddlers ended that experiment.
