looking for best isolation platform for CD player

Your tuning with timber and the result is a change in timbre accuracy. All are storage devices with various time delays and resulting colorations. Recipe for a soup sandwich with the resulting stains being tainted with each added ingredient..You have never truly experienced what is already yours..Tom

Try the SAP Relaxa magnetic levitation platform from Italy. The player is suspended on air by magnets and the effect is very good. I use the Relaxa with my Sony SCD-1 and my Krell KRS20t cd players

Levitation platforms are not immune to airborne resonances or to self induced chassis resonances. All noise will be stuck within the chassis. No common ground plane, no way out...Tom

I've found the Bright Star Air Mass products to make a noticeable difference, expecially when you crank up the volume and the bass energy in the room increases.

The most impressive system I have seen was at the Chicago Audio Society gathering a couple of months ago.

It is a 'stand' for lack of a better term that is designed to 'Isolate' (neutralize the degrading effects of ground borne vibrations) and to 'damp' (neutralize the degrading effects of air-borne vibration) the piece of gear.

Each one is designed for the particular piece of gear with which it is used. I don't know if the gentleman is advertising his product. Someone from the Chicago area might have more details.

Everything I saw about them was remarkable. All the info I know about them was from a paper called: "Isolation Systems for Audiophiles."
