I forgot to include in my earlier post, the Sub Plinth was Maple that was supported by a Kiln Dried Sand Bed.
The sand bed was set up, as a result of working with a CDP Isolation Platform.
The method incorporated had the most positive effect on the CDP.
I believe a very fine grade of sand was used, not sharp sand.
Another way to make a sand bed for a Plinth is to cut open a bicycle inner tube, seal one end, pour in Kiln dried sand, and then seal the open end, this method has been used for to control vibration on Telescopes and Long Telephoto lenses. It will be totally stable, as the moisture level of the sand will be sealed, it will be more user friendly than a bed of sand exposed to the air.
A really skilled type, where Hifi is concerned might be able to take this method a little further.
Slit the inner tube carefully, insert a small funnel, add Kiln Dried Sand, reseal the tube with a puncture repair kit.
Add a little inflation to the tube, or maybe that is taking it a little too far
