Best way to dampen a micro-vibrating Printed Circuit Board inside an amp? Thanks!

More audiophoolery! 

There are 'off the shelf parts' that are easily purchased, PCB Standoffs come with  Anti Vibration Designs. 

One of the designs discovered will be suitable for the role being selected for it.

A Part on a PCB that has a microphonic property that is audible can benefit, but it is better to treat  the Microphonic issues at the source of the noise, this has been known to remove the audible Microphonics.

Using the PCB anti vibration is not an issue, it would be 'belt and braces' if used in conjunction when treating a Microphonic issue. 

Oh please!

How exactly are you hearing/determining a board inside the amp is vibrating ? If this system is on and making music (causing vibration), how would you hear that the board is moving ?
