Look into the Mapleshade Audio solution. Used it under CDP's, DAC's and amps and have achieved wonderful results with all.
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?
