Mass and vibration cancelling on top of CD player?

What I meant was, in a sarcastic way of speaking, that most people would probably be inclined to say that level of the transport/disc is not critical since any unnecessary motion of the disc due to its non level condition during play or any other reason is accounted for by the servo mechanism that controls the laser when it gets off the nanoscale spiral data track. And, of course, Reed Solomon Error Correction Codes are supposedly going to correct any errors that occur anyway.

Got it. Thanks

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.

Thanks Dave. Interesting but I think far from complete analysis. There are probably more technical articles worth reading-if one knew where to find them. I think I will open the player and observe/feel for points of vibration and possible improvements.
The value of having put the vibration absorbing/reducing mass on top of the cd player is very apparent on all music. I am very impressed and pleased. It has added significant enjoyment to my listening. Nice cost-free improvement for anyone. The clarity, depth, dynamics and transparency improvements are very satisfying.
