The coupling or uncoupling issue is as yet unresolved. I am getting a pair of the new Townsend speaker cradles which uncouple the speakers. Presently, I couple the speakers to wooden floors using special tiptoes from the US importer of Acapella and have IsoClean pucks under them. I have heard the decoupling is far superior. I also heard the improvement when Beauhorn came out with a base that decoupled the Virtuoso speakers.
But since you are going with a coupling, I would say that mass over a very small surface, such as with tiptoes would be best. I would therefore fill the stands. I would also suggest that lead shot would be far superior.
