Cd transport isolation

I found that my Forsell transport was extraordinarily affected by isolation devices, which I never could understand but I actually could hear clearly. In my experience, the best isolation I gave it involved using an air and silicone-filled bicycle inner tube in a base that was damped with sand and lead shot, and putting that on either a Seismic Sink or a Gingko Cloud 10 platform. This combination did a good job damping the vibrations of the unit as well as isolating it from vibrations transmitted from the rack (since my entire front end is in a different room from the speakers, I had less of a problem with airborne vibrations than others might have). Unfortunately every inner tube I used eventually would leak (fortunately the base with the sand did a good job containing the mess), so I ultimately wouldn't recommend doing this anymore. I can't say that isolating the other transports I have owned has made nearly as big a difference as isolation did with the Forsell (that was one tweaky unit).

FWIW, after trying countless variations over the years, including some mentioned above, I have finally found extreme satisfaction with the following combo under my digital sources, (configured as the text is viewed)

-Front End Device
-Boston Audio tune Blocks (w/tungsten carbide beaings)
-SAP Relaxa magnetic levitation platform

These are mounted on a multiply decoupled very low mass lossy rack, the result of which has been a very apparent increase in soundstage size, dynamics and resolution, without any tonal shift.... and all up for very minimal financial outlay.

The most effective device I have come with for my digital system is a DIY platform using concave door knobs with ball bearings in between. More clarity, defined bass and more details. Easy to construct, (6) door knobs (Amerock brand)(3) 5/8" ball bearings amd (2) wood shelves cut to size resmbling your transport footing. Try it!

Thank you for all the responce. I will first try a DIY ball bearing system. And maybe play around with different shelve materials.

My dvd 50 sits on three Mapleshade Mega Mounts that's sitting On a thier 24"x18"x4" platform and thier Samson II isolation rack which has 4" inch shelves. Of the different racks I've used this one is the only one that actually made a difference in the sound of the system. The brass footers and maple platform makes a very substantual difference.
