Michael, you say that," ... when you dampen vibrations you’re also dampening part of the audio signal." In my system, parasitic resonances (all resonances are a form of vibration) such as those excited in the tonearm, are not part of the audio signal. So I damp them out. Don't think you can have thought this through.
You also say, "Another tip. Low mass frees the sound high mass squeeze the sound. The more weight and compressed mass your system has the more squeezed the signal will sound. The lighter mass you have, the more open the sound will be." Don't quite know what you are getting at here. Do you really mean that a high mass platter will "squeeze the sound?" If so, what do you mean by 'squeeze'? Is this a frequency effect? And what on earth is a 'compressed mass'? What is being compressed, and what force is doing the compressing?
