Do equipment stands have an impact on electronics?

"So like most things effectiveness of products depend on the context used and magnitude of the problem (floors with "give" versus inert rigid floor) which varies greatly It all depends as usual. Measurements or not."

eggs akley! That’s what I’ve been saying all along - Hel-loo! The seismic type vibration varies so much from location to location and even floor to floor, type of floor, local traffic, Earth seismic activity, etc. that trying to extrapolate or generalize measurements of a particular isolation device in a particular installation is probably not possible. There are too many variables. You’d have more luck trying to solve three simultaneous equations in four unknowns.

As I have also stated repeatedly the ball park performance of most isolation devices can be easily calculated from very simple equations. Performance such as percent of transmission that was provided for one of the isolation devices earlier in this thread. There is also the technique of mounting both the component and the isolation stand itself to consider and how much damping to apply to them. No one ever said it’s simple or black and white.

I suspect that when an isolation denyer comes up with negative results there is an excellent chance it’s a simple case of self fulfilling prophecy. Besides, there are many reasons why anyone can obtain negative or null results for certain audiophile devices. Shall we explore them?

LOL, so much hand wringing (Ethan's here, oh no! A definite turn for the worse) yet no proof that isolation does anything. Of course, as mentioned in my article, I'm not talking about turntables or earthquake level vibration. Just normal sound in the air from loudspeakers playing at normal levels up to and including loud "reference" level.

So again I ask, what proof do you have? More important, if you can't prove your case, doesn't it make sense to ask yourself *why* you can't prove it, and then possibly reconsider your opinion?

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.
