My own answer to MikeCh's question, since this is my post. ;-)

You ask "why bother?", and I can only say to find out if I can hear a difference in the sound or not, and, if so, whether the difference is an improvement in the sound or not.

Whether or not microphonics are what contributes to what makes tubes sound "good", I'd like to explore which, if any, anti-vibration devices improve the sound of my preamp and which don't and am asking those who've experimented with such devices (including footers, platforms and tube dampers) for their experiences because it's fun to discuss such things with fellow hobbyists and can be instructive.

It would seem possible to me that even if the slight microphonics that are inherent to any filament in a well made vacuum tube are euphonic, at some point microphonics become unpleasant and distracting, and that those might be caused by external airborne or mechanical feedback that might be minimized by a tube damper.

But that gets me to pigctureguy's response below, which has me questioning how tube dampers work in the first place (if, indeed, they do).
