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?

dl - I have a couple of comments on that measurements pdf:

1. The methodology is incompletely described, and there is no assessment of the accuracy, repeatability etc. of the Geophone sensor among other things.

2. Worst is likely the complete absence of sample sizes and any statistical analysis

There are several other problems with it, but there is no point in going on.

It could not be published in an engineering or scientific journal.

Geoff,

Like a displaced spring on a '58 Edsel your storyboard has sagged with age. 

Furthermore let go your LIGO as it has nothing to do with anything you make.

As you almost stated above..take a few days to think about it  and get back to us.

"Geoff,

Good one, Tom. You're on a roll.

"Furthermore let go your LIGO as it has nothing to do with anything you make."

Have to disagree there, Zippy. LIGO uses springs. 

"As you almost stated above..take a few days to think about it and get back to us."

Give me a few days and  I'll get back to you. I promise.

Randy, 

I agree. And to answer Dave as well..  Are we listening to a piece of music or the before and after affects of a pogo stick?  Plus it will work as a really good plug and not as a drain. Some energy has to be moved out from the source with speed and in an orderly fashion. If the internal interference lingers to long it will become a part of the original signal. Reminds me of so many others, one in particular...same concept slightly different materials. Tom

Hi Tom and Geoff,

If you would be so kind, could you comment on measurements pdf within the link I posted above:

http://www.solid-tech.net/products/discs-of-silence-4537455

That appears to be what I would expect from a low pass filter. Effectiveness of isolation rises as frequency rises, e.g., 88% at 20 Hz, 97% at 150 Hz. No surprises there. Also, good performance in z direction and x-y plane. Nice!
