Do equipment stands have an impact on electronics?

Mechanical grounding or isolation from vibration has been a hot topic as of late.  Many know from experience that footers, stands and other vibration technologies impact things that vibrate a lot like speakers, subs or even listening rooms (my recent experience with an "Energy room").  The question is does it have merit when it comes to electronics and if so why?  Are there plausible explanations for their effect on electronics or suggested measurement paradigms to document such an effect?

A spring will move above and below its resonant frequency. Tom

A spring will move above and below its resonant frequency.

Springs don’t have a natural frequency. They have spring rates. The device as a whole has a natural frequency. The frequency at which it moves. The more springs the higher the Fn. When you force a device to oscillate it oscillates at one frequency only. See if you can guess what frequency that is. Answer at 11.

Note to self: this is like shooting fish in a barrel.

That differs from what I just read in an online engineering journal saying a spring does have a natural resonant frequency. Everything has a natural resonance. Tom

As as I already said you cannot take the spring in isolation, as it were, it is the mass on spring together, forming a system, that is what matters. Therefore, it’s the resonant frequency of the isolation SYSTEM that determines its isolation effectiveness, not the natural frequency of the spring. And the natural frequency of the system is a function of both the spring rate of the springs and the total mass on the springs. You are one mixed up cowboy.
