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?

It does have potential merit as some electronics are microphonic. Tubes are vulnerable to microphonics and I once had a set of interconnects which were surprisingly microphonic.

I agree 100%.  I have had good results with tubed gear in particular.  I had a fire breathing dragon of a SET amp in a previous system, and I noted that the room stayed cooler (which the stand manufacturer, Starsound Technologies confirmed in their own experiments).

Some people also claim some capacitors can be microphonic or at least their is a theoretical piezoelectrical relationship between vibration and electrical performance, but I am not an engineer and have no idea of the veracity of such claims.

I've always found that stands with speakers on them must have zero back and forward motion, as the drivers move this way.
Any back and forward motion of the stand will be lost energy being projected into the room, being waisted by the drivers instead trying to make the stand move back and forward, even in unmeasurable amounts.
You loose micro detail and screw up your imaging.

they're not part of signal path.
