Black Ravioli
The problem here is, like other similar situations, you have two groups.
The first group have a firm belief that a certain product (whatever that may be) will not make any difference at all to the resulting sound because they believe there would be no difference in any measurements taken. Therefore, it is all BS and those that have tried it and heard a difference and are living in a different world where science doesn't exist, so are open to ridicule.
The second group are those genuinely into music and hi-fi. They are open minded enough to try it, whether it makes a difference or not, and decide for themselves by actually listening to see if it does make a difference.
Well put.
I would argue however that there is a third group who are open minded enough to try it, decide that there is a difference after listening, even when there is no measurable difference to the sound at all.
As all perception is subjective, it becomes a philosophical question if a listener perceives a change whether that change is real. It is certainly real to the listener, and ultimately that is all the listener cares about.
So it is quite consistent for one individual to say that there is no audible difference, there to be no measureable change, and another to say it sounds better to me. Listening is done with the brain, not just the ears and is the result of many inputs, not just pressure waves on the eardrum.
As an engineer, I know that there are many products which don't have a hope in hell of making a difference to the sound produced by the speakers, but if it makes the sound better for you, who am I to argue?
It's obviously well known that there can be measurable differences that are not audible. Does anyone know of a documented case of a proven audible difference that cannot be measured?

Sound fair?
A forum should be for open discussion rather than ridicule (there's plenty of specialist forums for that), so its members shouldn't be stifled by those that are waiting to pounce on them if they are open enough to admit to trying something and hearing a difference. Feel free to state that you think a product is voodoo and why you think it is voodoo, but I think trying to run literary rings around those that have tried it to make them see an end result as predicted by those rubbishing the product is wrong, and just leading to a forum where people are scared to air their views or ask particular questions.
No it isn't fair! There are many music lovers like me who generally look for objective measurements and who very much doubt the smoke and mirrors stuff that is associated with hifi. I don't love hifi though! It's simply a means of allowing me to hear music. I know there are people who it seems love hifi for hifi's sake and that's fine but it's not for me.

A voice of educated reason, perhaps ?
To counter the effects on the gullible, by the advertisements of quackery ?

Oh David, please do get over yourself. This is one of the most pompous and inaccurate assessments I have come across.
Listen with your ears, don't try to measure, there is equipment for that.
It seems only those with golden ears can enjoy and love music.
Just my 2 pence worth. 
Last year I tried Black Ravioli in a shop and couldn't hear any difference. I tried it with both solid state amplifiers and a valve amp and it made no noticable difference to the sound.
I also tried putting the amplifiers on top of the speakers (without any Black Ravioli) and played bassy music to maximise the vibrations being transmitred to them and even this didn't make any difference to the sound quality.
My conclusion from this experiment is that a small amount of vibration shouldn't have any effect on an amplifier. If an amplifier does sound different when it's vibrated a little bit then it should be avoided IMO.
Crumbs!
Black Ravioli must be loving all this free publicity!

I remember, but it's not quite the whole story.
When I asked about the demo, you said the shop guy had placed the pads under the feet instead of under the chasis. If placed under the feet it has little or no effect, and I pointed this out at the time.

You are more prepared than most to give stuff a try, but whatever chance this has to work, it needs to be used as instructed.

I do intend to give them another try with them placed in various different positions. One day soon...
