The word "microphonic" itself is a little ambiguous as even tubes that are referred to or marketed as non-microphonic are in fact slightly microphonic, which can be easily demonstrated by using some effective tube dampers. Furthermore even things like circuit boards or cables or solid aluminum chassis that are not "microphonic" or considered to be "microphonic" are susceptible to vibration when excited by their resonant frequencies. That’s the case whether the component is tube or solid state. Funny story. A friend of mine said watch this. He was sitting in a chair on the other side of the room from his stand with a CD player on the top. Next to the CD player was a glass of water. Next, he began tapping his knee with his finger very softly. Immediately ripples appeared on the surface of the water in the glass, synchronized with the tapping.
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?
