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?

Well if you agree that tapping components is causing vibration in the components and if it makes absolutely no audible sound out the speakers at full volume then you have almost certainly proved that vibration is not a big deal.

so it definitely proves something

yes, it means microphonics is not the issue. It’s something deeper. Because vibration degrades CD laser reading and distorts the signal in everything it’s a BIG DEAL. Microphonics is a strawman argument.

Seismic type vibration forces the ENTIRE BUILDING to vibrate. Because seismic type vibration is not unidirectional, but has 6 DIRECTIONS of motion, everything in the building that is sitting on the floor or attached to the walls or ceilings is vibrating in concert with the complex motion of the building. That is why, in order to escape the effects of seismic structural vibration, the components - even solid state components - must be isolated. Nothing is really inert unless it’s decoupled from the building. Thus, even a three foot thick steel or aluminum bar sitting on the floor will vibrate.

Geoff,

The burden is on you to make a simple demonstration to show that vibration is a big issue. Cars and other mobile devices do not suffer electrical distortion due to vibration of electronics. You are talking about a fringe issue that is obviously rare or we would encounter it more often on a daily basis.

Huh? Portable devices like Walkman as well as car CD players employ data buffers to avoid the effects of walking, jogging, driving etc., which actually illustrates that vibration IS a problem for all electronic devices. Thanks for bringing that up.
