How do vibrations affect the equipment?

In the same way. Simple as that.

Vibration control is a dark art. I've always used what I thought were decent Target equipment stands, solid brass cones and various vibration control devices placed under equipment. We all know them.

Then I started using a Sunoko Vent stand and really was astounded by the improvement. Shared the experience with a shop I occassionally do business with and he laughed. He said they had taken in a used equipment stand and pleyed around with it, he stated "you could have set a polished turd on it and it would have sounded better".

It is a strange thing.

Try Symposium Roller Block Jr HDSE big sound upgrade,better bass,stage,imaging.

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?
