Paul,
In another thread you started http://forum.audiogon.com/cgi-bin/fr.pl?htech&1370624240&openflup&25&4#25.
a few of the questions and answers were stated.
Because isolation only exists in the absence of matter a sand box only serves as a high impedance storage device that will trap airborne vibration [your music being played] as well as internal resonance of the reproductive device. If you impede the fact that energy is in search of ground and use so-called isolation materials and methods you have filled the energy bucket with murky water that will become darker over time and fill faster than it will leak out. The device you are trying to benefit will be colored by the chosen [isolation] material, mass and geometry.Tom
