component cones/spikes vs. rubber


I'm trying to decide whether I should put cones/spikes or Vibrapads/pods underneath my woodshelving which is directly underneath my components?

(Note: I currently have wood shelves underneath my components so the spikes/pads will be placed in a platform config. All of the above will be sitting on an audio rack)

Components:
1. Cary CD player
2. Audible Illusions 3A pre-amp
3. BAT 75SE tube amp

Appreciate any comments/thoughts?

Thanks,

Do you want to couple or isolate? They will both work but give different results. I use a mixture of cones and roller bearings myself but preferences here will be system and taste dependent.
Because tubes can be sensitive to vibration induced micro phonics I isolate all of my tubed components with absorbent supports. Some folks like this (subtle) micro phonic effect. Some don't. Your choice.

If you use heavy spikes into a massive board it will effectively dampen vibration which I find sounds best with my all tube amplification.
