vibration control - cd player

I heard a demonstration where different levels of vibration damping platforms and couplers manufactured by Symposium were employed under a cd player.  The first two levels brought improvement to the sound, but, the highest level of damping made the sound too lean and analytical.  This was the unanimous opinion of the people hearing the demonstration (including the representative from Symposium).

Here is a link to the (old) discussion of using Ikea Lack tables as support for hifi gear (pay special attention to the posts by caterham1700 - who owned Greater Ranges/Neuance).

If the construction notes/guidelines are followed you can expect excellent results (better than that of many of the commercial footers/platforms I’ve tried in the past)

Nordost Sort Kones BC.  Better than isolation. Drains vibration from the CD player itself.

Creates a dead quiet background, lets the music really shine.

No matter what you put your gear on rack-wise or any footers you will hear a change in the reproduction like cables you have to try them and see if what you hear is what you like. I've used many racks over the years and footers, the footers all gone, and my gear sits on the feet the product was designed for. BUT my rack and amp stand that I settled on after many years of experience has stayed now for 10 years. Nothing between my speakers but the amp stand rack on the other side of the room.

Trust the designer of the CD player and do not waste money to reduce vibration (in your brain). If you're that concerned ... find a rock or some weight and put it on the player
