Do equipment stands have an impact on electronics?

Ethan stop by my place and we’ll have a listen as proof. Cheers!

In lieu of that,  in rooms where I hear a difference I can jump up and down and feel and hear floors vibrate.   In ones where I don't hear a difference jumping does nothing.  That proves the vibrations are transmitted to the floor and in some cases (not all) can be heard.

Your tests in one room do not prove anything about another either.    You might not hear or measure anything in one yet do so in another.   As you know no two rooms are usually created equal.  that goes for the floors as well.


Does that make sense?

Where is your room? Near me in western Connecticut? I’m always willing to drive up to an hour each way, or even two.

But otherwise, no, it doesn’t make sense. Just because you can feel your floor give when you jump up and down is unrelated to whether loudspeaker isolation improves or even changes the sound. Did you read the article I linked? I explain all of this, and why, in detail. And as I said at the end of the article, I’m glad to see measurements from others proving that isolation does make a difference in their situation. But so far nobody has. And calling me ignorant (not you, others here) is hardly evidence. Nothing audible that happens in a room will evade measuring with the type of software I used for my tests. So yet again I ask for measurements. As Judge Kevin Ross says at the start of each TV show, "Prove your case!" :->)

No, Central Maryland.

The only gear I have to do any tests is my ears. So I know its possible.  It is not subtle at all, perhaps one of the clearest and most obvious differences/tweaks I have heard.    The jumping test I indicated shows that it is at least possible as well. I suspect its fairly common even.

I don’t expect you to believe me though given your criteria for acceptance.

Its most apparent listening with my OHM Walsh speakers that have downward firing ports but I hear it as well with small Triangle and Dynaudio monitors in 12X12 room on second level. In same size room below at foundation level, I do not hear a difference.

That should at least make sense. Whether you believe it can be heard or measured otherwise or not is another story.

Also I would say that my explanation could account for what you measure in a single room but your measurements in a single room cannot account for any others.

In any case I hear what I hear and know what I know and I’m sure there are others with similar experiences. Bring your measuring gear on down and we can perhaps both learn something together. Or try some more tests on your own. New discoveries can happen anytime.

I've been a professional audio engineer and musician for more than 45 years, and deeply into acoustics for the past 20 years. So I have a good handle on what happens in rooms, how things sound and are measured, and - maybe most important - why people think they hear stuff that isn't real. Now, that might seem controversial or even insulting, but you probably know that there's an entire scientific field called "psychoacoustics" that deals with this sort of stuff.

So, as always, the burden of proof is on those who put forth a theory, and after more than ten years of asking for proof nobody has ever shown any. Not once, not ever. Ask yourself why that is.

Ethan, I think room acoustic software is a reasonable endpoint to measure.  There is freeware available to use to this end if people are so inspired.

Here is a video from Townsend that was circulated earlier in this thread as proof of concept but it in no way measures endpoints that are meaningful:
