Vibration control. Tube equipment. What's the best way to do it ?

HRS. Although I found the positives varied greatly from component to component. 

sns, I see. It would be interesting to experiment with various woods. Ebony or Brazilian Rosewood isolation platforms anyone ?

@inna You often see speakers and turntables made of various woods, esthetics for speaker I imagine, people report differences with turntables. I'd think there would have to be a pretty wide variation between wood densities to hear a difference.

Maybe one day I'll try these Ansuz Darkz. It certainly seems ridiculous to put $3000 worth of footers under a $3000 component, but under a $30,000 CH Precision pre or amp or an Antipodes Oladra I could justify it. 

Ebony or Brazilian Rosewood isolation platforms anyone ?

I have read glowing reports of Shun Mook Mpingo dots, which is African ebony I believe, just on tops of speakers, and on walls. Haven’t tried it yet.

Here is Jeff from High Water Sound at a show over 10 years ago- see them on the top of the Hornings.

I suppose this "tweak" falls beyond the concept of resonance control, and into the topic of acoustics though.
