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 use the FIM saucers with tungsten carbide balls as well. Shelf resting on top of the ball bearing (rather than another saucer).I use a different shelf material though.
