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?

Thanks Robert, I'll look into your products. Some of the drum company's have introduced accessories designed to allow their drum shells to resonate as long as possible (sustain is very "in" right now in drums), by suspending their mass in free air. Mounted toms holders are no longer mounted directly on the toms' shells (metal parts bolted onto drum shells seriously affects their ability to resonate), but are instead attached to the drumhead hoops. Pearl offers rubber feet for floor toms legs which contain an air pocket designed to prevent the shell from being "grounded" to the floor, robbing it of it's full vibrational resonance.

For hi-fi product support, isn't a lack of resonance the goal? And whatever resonance (vibration) is inevitable to be prevented from entering hi-fi components? Absolute isolation may be an unreachable goal, but it's a correct one imo.

I use Robert and Star Sound on every piece of my equipment tt,phono amps, power supply,conditioner,trans, dac ,spkrs, stand and subs.Works like a champ ...my stand is filled with micro bearings ,the points are rock solid .let it vibrate ! jmho

Shear waves do not travel thru the air so they cannot be a part of your acoustic waves...

That is correct.  They do propagate in any fluid, only solids.  The guy arguing with you above is completely wrong.

As side from the obvious grammatical errors in your statement, "they do propagate in any fluid, only solids," any wave can propagate through a solid OR fluid. That is why we have shear waves and shear forces in air. And why there are shock waves in air. Apparently you fellers don’t know the difference between a force and a wave. Acoustic (sound) waves - the ones that travel through air - are mechanical waves, just like waves in solids. And sound waves travel through heavier liquids like water and even solids. In fact sound waves travel faster through heavier liquids and solids than through air. And that’s why, in terms of their effect on components, insomuch as they are mechanical waves, acoustic waves produce vibration in components. There is no difference - in terms of their *effect* - between the vibration produced by acoustic waves and the vibration produced internally by transformers, motors, etc. I consider this particular case closed.

Shear waves have a polarity that travel at 2 different speeds.each .slower than the primary wave. Also travel in 2 different directions. Tom Star Sound Technologies.
