looking for best isolation platform for CD player

i tried as a platform (under my cd players burmester969,C.E.C tl-0 mk2,metronome Kalista) vibraplane,symposium,polycrstal,hrs,acapella.(any many different spikes,rollerblocks,Q damper.....).i think platforms (like a cables)depends your system and your taste.
i prefer symposium,polycrstal and acapella over vibraplane and hrs.
also shunmook Mpingo disc was wonderfull on burmester 969
Now i will try grandprix monaco

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.
