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?

I was just checking this tonight, my CD player is on a Star Sound rack equipped with large cones for coupling to units to the rack and draining vibrations quickly. But I got a better result putting the CD player on a marble tile resting on 3 tungsten carbide ball bearing resting on 3 FIM saucers. I sell both so not partial. This result applies ONLY to my system at the present time.
CD players are also mechanical devices as they depend on reading a moving disc so vibration will have an effect on them. Note the effort by some of the top players to deal with vibration by floating the components on the chassis. I have my TT and CD on roller bearings and the rest on the Star Sound cones. The thing to bear in mind is that ALL of these things "work", i.e. change the sound. Which is best varies from system to system and owner to owner. And from time to time, I have changed my mind about which I prefer more than once.
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.
