Perhaps this is what you were hinting at regrading resonance graphs below?The web site claims these will 'absorb' frequencies down to x, but they don't bother to state what the level of attenuation is. This is pretty useless info if you ask me (I do realize you didn't!).
From the information offered, there is absolutely no way to determine even the potential effectiveness of such a device.
Your post does make for some interesting discussion, though. Among other things, it's quite obvious that many people still believe for some reason that placing their gear on something as rigid as granite can somehow contribute towards isolation. Rigid materials do not isolate, regardless of how heavy they are; in fact, they do just the opposite: they couple. Coupling is a necessary part of any vertical vibration management scheme, but if you believe rigid materials isolate, you're not managing vibration, you're just hacking.
This isn't to say placing granite under components won't change the sound of the component, and sometimes for the better, but this should not be confused with reducing the total amount of vibration traveling into or out of the component - you've only changed the nature of the component's environment relative to vibration.
