This seems like an ironclad proof to you?Well the person in the forum link who uses that technology lives in the US and has always had a suspended wood floor so that must shoot that theory.

I sold a lot of Sound Organisation stands demoing how they improved the performance of Naim electronics so your welcome to believe what you will.There's a great video from HP showing how much vibration it takes to upset their measuring kit, think hammer action drill on the casework not being able to throw the scope off one iota. Solid state gear is pretty much all immune to less than superhuman amounts of vibration. Crystal oscillators and compact discs excepted.
Hi Fi supports always improved performance whether on concrete or wood floors based on my experience.This seems like an ironclad proof to you?
I don't follow your logic.
If your goal is to learn about the science involved then I would definitely avoid the typical audiophile sources such as magazines, forums (perhaps with the exceptions of ASR and DIYAudio) and above all marketing blabbering from manufacturer websites.
But that’s me.
I think my experience has generally been positive with tube equipment, but generally no difference with solid state.Hi Fi supports always improved performance whether on concrete or wood floors based on my experience.
The only isolation I bother with is semi-inflated tyre inner-tubes under my non-suspended turntables. I believe I can sometimes hear the effect in the tightening of bass notes at high listening levels.
I've only just wandered into this thread, but if your stand vibrates, doesn't that mean it must be coupled to the cabinet? And as such can return the vibration to it?I am a protestant too. If you let your stand to vibrate it means that this amount of vibration is physically removed from your box/cabinet - and it was the main goal, wasn't?
Turntables, valves, bad connections and CD transports can benefit from isolation as you would expect.

OK, the turntable does have a coin under one foot to ensure it is level and doesn't wobble. I would have said 'rock' but then I don't play a lot of rock music anyway...

Simple physics.
BTW is anybody interested in the actual physics of stands under loudspeakers?
Please imagine:
There are the stand + speaker and an air-cushion between them; I think you see that stand / speaker will be isolated quite well; speaker-resonances won't shake the stand; the 'all-system-resonances', (an amount of vibration) let be 100 units; cabinet will resonate 95 units; stand has 5 or so.
If you use an ultra-light metal stand, I think the values can move around 35/65 or 45/55 stand/cabinet ratio, I do not know; maybe 25 only or less.
The important thing is, that these 25 or 35 or 45 or any units are came from the all-system-resonance; it means that your cabinet will resonate less then previously with the air-cushions.
Means, here the stand-vibration is the 'resonance-remover'.
Simple physics.
When you use a heavy stand, the situ is vica-versa; because the resonances delivered by the mass-ratio, stand won't be resonated so much, your cabinet will do it.
And what about the singing stand? (my one sounds almost exact 'E' when fluffing with nail)
These vibrations are not in direct contact with the drivers and after the transitions they will be 'out of tune' compared to the original cabinet-resonance so won't disturb the performance.
Any contras?
P.S.
1. It's an extremly simplicied explanation.
2. Of course, there are some more complicated situations. I mean the sand-filled metal stands where the resonance will be adsorbed by sand. But the mass-ratio in the 'resnance-removal' project will have the same importance.
