If you want the best then you sould search in a device which couples any vibration to your floor in an efficient velocity. This is extremely difficult to be done and requires many years of experiments, A/B listening tests and measurements.Theoretically, any audiophile gear should operate in a vibration-free environment regardless their origin (endogenous or exogenous). In my point of view, the only way to provide a vibration free environment is by preventing of the spread of floor vibration to the equipment with simultaneous and immediate coupling of the internal and air vibrations to the floor. I underline the word coupling because this is the most crucial point in which one product excels over the others. Everything else is variations on a theme of damping, making vibrations (=kinetic energy) recycle in the shelve mass since the conversion of it to thermal energyis completely inadequate. So, in my opinion, every damping effort is almost fault and wasted from the begining.
