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?

OK, back to business. A brief survey of vibration isolation and coupling devices by Galen Audio is linked below.

Note that Golden Sound DH Cones which are the extremely hard NASA grade ceramic cones are mis-identified as from DH Labs. Also notet that the Galen Audio survey is by no means complete as there are many important isolation devices missing, including but not limited to Vibraplane, Minus K (negative stiffness), Symposium, Halcyonics, the new Townshend iso devices, Shun Mook Diamond Resonators, bicycle inner tube, an example of constrained layer damping device, an example of mechanical (steel) spring based device and Mapleshade’s system of air dried Maple plate and brass cones.

The survey does not consider hybrid solutions such as spring and roller bearing combo, dual layer mass-spring devices.

Geoff, you are an engineer.  How would you propose measuring the results of said products?

We’ve already been through this. I’ve already answered this question. At least a couple times. Since you're so enamored of this question why don't you tell us how you would measure it.

Cheers
I'd use laser interferometry or at least a vibrometer to assess the actual movement of the stands and at high volume on a variety of music and frequencies.

THEN, I'd use a driver to force the particular electronic components at those vibrations in the x,y, and z planes at greater amplitudes than found while listening to be sure.

That’s nice but the OP is asking how you would measure the audio performance. Anyone can measure the relative motion. All you need to do that is a glass of water.

Then Randy-11 wrote, in his best fifth grade grammar,

"you turn, geoff"

I’ve already described why I think it’s fruitless to pursue the whole measurement thing for iso devices. Were you sleeping?
