I used to use bricks (6 to be precise) on top of the CD player. It just looks ugly, though. As an alternative, I took the player apart and used a vibration-damping adhesive popular in the car-audio industry: Dynamat. You simply apply it anywhere in which it won't inhibit the natural function of the player--everywhere. It can be purchased at either Best-Buy or Futureshop, I do believe, and is a more aesthetically pleasing than bricks or other materials on the player. Also, if you can use footers with similar hardness between the bottom of the player and the stand surface, it should aid in draining other vibrations away from the player. The effectiveness of the latter will obviously depend on the materials and implementation involved.
