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,

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.
"DING" the winner is, Mechans, If you use Spikes, or better, pointed brass Footers, you will have a path for vibrations to leave the componant.
If you use soft rubber pucks, or similar, no vibrations will get into your componant, BUT the one`s you have will never get out, either.
They all sound different....not better or worse. Also the materials that they are crafted from affects the overall performance. Brass sounds different than steel, etc. You have to hear it in place in your system to determine what is best for you.
