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?

I also have a Star Sound rack. Also several of their cones. Very rigid and heavy! All of them sound different. The MIG supports work very well. 

We know how to remove interfering energy without removing needed polarties of shear as does your product and like designs. We keep the good because they are required for accurate reproduction. Your designs create a mechanical barrier on which any voice coil loses articulation while trying to overcome your materials of cancelation.  Tom. Star Sound
Motion artifacts can be seen as well as heard. Maybe you cannot seem them in the video link because you didnt look or there are none there to see..Tom. Star Sound
The audio weak,

Speaker feedback is not a problem only if the audio engineer is smart enough to employ isolation. Otherwise some feedback is inevitable.

The video you provided shows how someone can perform the water in the glass experiment incorrectly, although I have to confess I didn’t think that was actually possible. The lemon, ice and stirrer damp the vibrations that might otherwise appear and the glass should be filled to the brim since the ripples appear in the surface of the water. It’s not rocket science. At least you tried. Lol

helpful hint: the ripples that appear on the surface are a little subtle, it’s not like water is sloshing around in there although someone might be sloshed.
