AA PRIMA tweaks ......

I have the latest Sony mechanism AA Prima cd player and have added the following:

1)3 Adona brass cones and feet under the player(very inexpensive).Two in front and one at the back.Walker Audio tuning puck ontop of the player.ERS absorbing material(two sheets) over the tube area of the player.
2)Signal Cable Magic Power Digital Reference powercord(4 feet)
3)PS Audio UPC 200 power conditioner.

Try these,or similar, tweaks and you will be amazed with the results.I certainly am ....

I see the "surroundings" as the rubber washer, in addition to the rack.

Arthur,rubber will not really lead to the disposal of any vibrations from the cd player to the rack,but may of course lead to dampening/absorbsion of any vibration from the cd player.The rubber,will protect from vibration from the rack reaching the component.I guess this also depends on how hard the compound of the rubber is.I used squash balls cut in half under the feet of an hybrid amp ,at one stage.It did make a difference.

Funny,a while ago ,I thought this whole "vibration" control issues were nonsense, until I tried it myself ...

Exactly. I have a collegue that does research in elasticity of materials for dampening and I can tell you that even the slightest differences in material type and characterisitics will affect entirely different mechanical frequency ranges. It is luck of the draw without highly specialized equipment. Once again, empirical determination is the best way.

Bluebull and Aball, thanks for the suggestions.

My audio/video rack is a large solid wood coffee table (3x5' with solid wood 1.5" top and 4" solid wood legs)with a 75 lb 42" plasma monitor, 30 lb amp and other audio components holding it down. I place the amp and CD player on the top in front of the plazma. I don't know much about vibration, but with 100 lbs of components sitting on the top of this solid wood rack, in your opinion, will I still have vibration issues? Thanks in advance for the advice.
