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 ....

Edcook - I use rubber washers from Lowe's between my cones and Prima. Solved the problem for me, all at a cost of $1.20.

Hard contact between cones and player is questionable anyway. Rubber is a necessary ingredient for proper damping IMO. Arthur

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

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.
