Vibration Theory - Isolate or Drain?

Cruz,

Thanks for asking..

So called mechanical isolation is a kin to cap coupling in electronics. Cap design and their material makeup are coloration devices as are materials and geometry chosen to make so called isolation devices. All of these are filters of sorts and there is no such thing as a perfect filter anymore than isolation is perfect or even possible except in the absence of matter. Because isolation is not possible...I have in my system applied extensive resonance grounding methods to all my components. I have dis carded all soft materials and replaced them with hard materials that are then mechanically grounded to the higher mass of the floor. Mechanical resonance drain..I find these methods very realistic and musical..

I use both methods and they both work, but do not sound the same. I have not had good results with rubber or Sorbathane [sp?] to the same degree. For instance when I took the rubber feet off VPI turntable motors and replaced them with small brass cones it improved the sound; also replaceing the stock feet with their rubber washers with solid brass cones was a large improvement.

"All of these are filters of sorts and there is no such thing as a perfect filter anymore than isolation is perfect or even possible except in the absence of matter. "

Hmmmm....that would probably explain the proliferation of vibration isolation devices for audio applications in the past 12 years.

Paint by number, flavor of the month, retune your system because you don't like it today, mix and try to match, hodge podge, soup sandwich...greed, great marketing.
All based around the misuse and misapplication of the word isolation. Crying out loud.. Vibration can be given direction to ground..and has for more than 12 years aahh since the big bang. So called isolation devices and associated materials only interfere with the transfer of energy to greater mass. My preference is material grounding because it is predictable, consistent and musical and works outside of the impossibility of isolation. Tom

Perhaps you don't acknowledge or are dismissing the transfer of seismic/structural vibration to the component. I mean, that's really the whole point of isolation. isn't it?
