I haven't done the vibrapods under my Oppo BDP-83 but I did do mass loading on top of the player. 2 5 lb plate weights along with a sheet of Acoustimat under the weights. It definitely helped with the vibration when the BDP-83 is playing any kind of Blu Ray movie or CD/SACD.
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?
