Wood blocks underneath components?? snake oil?

Newbee, the reason I thought of frequency response accross the audible spectrum is that I am not sure how else to quanitfy an audible change at the listening position. I suspect it is this difficulty to quantify that brings everyone back around to DBTs, which I suspect would be hard to set up for resonance control products. Nonetheless I DO use resonance control devices in my own system with my turntable. I think the Walker Resonance Control Discs improve the sound, but I suspect I might go mad trying to find the exact difference with and without.

The Kid (Chris): you said you were blown away by what it did to your system. What exactly did it do? what sonic impact does it have on your components? I assume you found some real audible changes. What were they?

You guys are putting me on, right?

Kenyonbm, nope. This is serious business for some. I checked your system, beautiful. You ain't missin a thing.

To all non believers;

If you tap an electronic component, circuit board, tube, etc. it will be amplified and you can hear this come through the speaker. This is not open to debate, it is a fact that can be easily demonstrated. Some tubes are so susceptible to this that just speaking loudly near the tube can be heard through the speakers, but all components are affected to some degree.

If the vibration induced in the component by tapping is audible, isn't it logical that any other induced vibrations such as those being fed back from the speakers would also be audible? If I change how my equipment vibrates by damping it or some other means shouldn't this also be audible?

This phenomenon is firmly rooted in the scientific principles of basic physics, not snake oil.
