Do equipment stands have an impact on electronics?

Wait and you will see agear.

I use the isoacoustics stands tested in the article. The difference they make in my two rooms on second level with suspended plywood floors are clear and distinct. Anyone can hear it.

Same stands in rooms on foundation level make no difference.

Same results with auralex subdude platforms I use under bottom ported Ohm Walsh speakers.

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?
