How do vibrations affect the equipment?

Vibrations can affect the signal. 'microphonic tubes' are a classic example.
Other parts can also be affected by vibrations and affect the sound.
Lots of hearsay about dampening the component chassis affecting the sound.

Thank you all for your responses! I still do not grasp how vibrations can affect a SS amplifier (no problema with a tube amp)or rca cables or spk cables or a dac, etc. Can someone explain the physics of this phenomenum?

I doubt it. And I suspect that any explanations that may be offered would involve effects that cannot be proven to be great enough to be audibly significant, and therefore would be speculative at best.

The vibrations are reproduced by the speakers and then make you vibrate. :)

Actually, I think it introduces electronic jitter into the circuit, which degrades the signal as it works its way through the rig. In the case of tube gear, there's an additional problem related to microphonics, which as the word implies, is mechanical vibrations affecting the operation of the tubes and their output.

The point is that many audiophiles try to dampen mechanical vibrations reaching the gear as much as possible. I'll leave to our tech members to wrap what I just explained with techno-speak. Hopefully, none of our wise guy members will talk about "quality electrons" again.

Vibration control is a science very similar to room acoustics relative to the use of absorption/diffusing materials. The cheapest best tweak I ever used are the Vibrapods isolation cones. They are relatively inexpensive and will improve significantly the stability of soundstage/imaging and bass dynamics. I started using them first below my CD player and put them basically under every piece of audio gear in my system.

Without these, music is like an unfocused camera lens, put some vibration control devices and music comes back focused and articulated! It is really a no brainer to me and as important as room acoustic treatment.
