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?

emplying devices under or on top of a component, is a form of tuning, like a tone control. since no stereo system is perfect, hard or soft objects will affect the frequency response. i would conjecture that the choice to absorb or drain is subject to personal taste.

i prefer soft objects, because i find that usuually, hard materials, "harden" the sound.
The measurement of discombobulation when using a complex collaborator to discombobulate vibration complications is ludicrous when signalling metros anomalies.  
I isolate the massive base, then drain to it. Mass load each piece of equipment. Seems effective.
