Hi Gaffer,
A tube that is exhibiting a microphonic condition adds an unwanted contribution to the signal flowing through the component. The microphonic signal added to the original signal takes us further away from faithfully reproducing the instrument that has been captured in the recording.
A tubed component that is subjected to floor-borne vibration that is entering through the equipment support can cause tube microphonics. In addition, air-borne vibration that is striking the component's chassis as well as internally-generated vibration (transformers) may also be contributing. Isolating the component from the floor-borne vibration and restricting the other two forms of vibration as much as possible will minimize the problem of microphonics.
Some vibration control products allow the component to resonate freely or do not restrict the air-borne or internally generated vibration from affecting the component. This allows the signal to become contaminated. Once that occurs it will be impossible to restore the signal to its original, unaltered condition.
