I have recently coupled my system so that all components are tied to my rack to drain and WOW it does make a serious improvement. It's called RTS Coupling from Audio Horizons. Over they last 20 years I have tried many ways of controlling vibrations including Herbies, Nordost, Eichman Toppers and many more. The improvement from coupling is 20 fold to any other device I have ever used. I only listen to CD's and what I have noticed is more micro information, more body, sense of ease, more dynamics, more of everything good and nothing bad. A very inexpensive way of making a HUGE improvement to any system.
Vibration Theory - Isolate or Drain?
Given that a CD Player or Transport has quite a bit of internally generated energy from the motor, is it best ti deal with vibration issues by coupling the player to a surface with spikes or cones? or decouple the player from the surface beneath it with spongy materials? Any consensus on the best approach here?
