For my MW/Oppo 83 I use 3 vibrapod cones. They are $8 each and provide a dramatic improvement of clarity and detail. I tried their vibrapod isolators and they made my rig sound warmer, which was not the direction I wanted to go. I also tried a combo using both stacked- with the cones on top of the isolators. This combo provided a nice marriage of both characteristics which I really liked. My rig ultimately sounded best with the just the cones. Also know that there was some users who found that vibrapods produced a ring on the rack table. To counter this I use small index cards underneath the cone and this protects my rack.
