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?

Okay, one more, I can’t resist:

"We had an interesting incident near Humboldt State University. A new cell tower went up and the local newspaper asked a number of people what they thought of it. Some said they noticed their cell phone reception was better. Some said they noticed the tower was affecting their health. Think about how much more pronounced these effects will be once the tower is actually operational. The ability of the human brain to convince itself of just about anything is not to be underestimated." --Brian Dunning

But no one is saying there can never be placebo effects or other types of psychological phenomena in audio or any other field. Your problem is that it’s a logical fallacy to argue that those psychological phenomena conveniently explain *everything* you happen to be skeptical about or whatever.

No, the burden of proof is on those making the claim. Logic 101 teaches that you can’t prove a negative.

That’s illogical, Captain. Actually, in the real world the opposite is true. In a court of law the defendant is not required to prove the plaintif’s case. It’s up to the plaintif, you know, the one bringing the charges, in this case the charge that the device in question is a hoax or fraud, who’s actually got to prove his case. So far all we’ve got from the isolation denyers is a lot of angst, drama and who shot John.

But Geoff, you’re the plaintiff. You are the one denying what science knows about how sound propagates, and what my article has proven, so it’s up to you to prove my article is wrong. You know you can’t do that, so you try to convince yourself it’s up to me to prove my case. I already did! Read my article again. Look at the graphs. Boom, there it is: proof that loudspeaker isolation is nonsense. There was more change from lowering the speaker three inches than from any of the isolation devices!

All you have to do to prove that isolation improves the sound is to measure your own isolation situation or whatever you have. Do you know how to do that? If you email me from my web site I’ll be glad to help you. Or start here:

It amazes me that people will argue and complain for literally years, when all they have to do is spend half an hour measuring to prove their case. Just think what a hero you would be if you could prove that isolation devices improve the sound! Heck, I’ll give you $100 if you can prove that. I really will.

I proved my case or at least offered good evidence. If you jump on the floor and hear a corresponding sound or feel corresponding movement guess what? Movement caused the floor to vibrate and make a sound.

Or play music with a good subwoofer or other speaker with good bass and use the aforementioned water test or just listen and see/hear. Its not rocket science.

In fact its a much easier and cheaper problem to address than room acoustics/room nodes. An Auralex subdude platform costs less than $100 and is very effective when needed. Maybe that's what Ethan is afraid of?  Cheap competition is a bugger.

Check the testimonials on Amazon or other sites. Are all those people deluded? Ethan apparently thinks so.
