"Isolation prohibits the evacuation of resonance formed from vibration.

This establishes tremendous component operational inefficiencies as this resonance also propagates on all smooth surfaces clogging all signal pathways (electrical, electromechanical and acoustic) per Coulomb’s Law."
Robert, as I already said damping is necessary and sufficient to deal with (medium and high frequency) vibrations that show up on the top plate of an isolation device, whether produced by an internal motor, transformer, CD transport mechanism, acoustic waves, etc. BUT this is in addition to isolation which is necessary to deal with the *very low frequency* structureborne vibrations. It is not true that isolation prevents the internal vibrations from escaping the system. The trick is to properly isolate and properly damp without over damping. If there were no such thing as isolation or if isolation prevented vibrations from escaping the system, as you say, then the LIGO project would never have been able to detect gravity waves, the amplitudes of which, by the way, are on the order of the diameter of a neutron. In fact, LIGO would never have been able to detect gravity waves without vibration isolation. Period. Surely your seismic expert knows that.
I have almost always used vibration dissipation, "mechanical diodes" and damping techniques in conjunction with or integrated into my isolation platforms, including my sub Hertz Nimbus platform. It is not exactly a big secret that damping of the top plate is important.
I have had many discussions with Michael Green of TuneLand and Michael Green Audio, who preaches a very similar message as yours, that vibrations should be allowed to flow freely in the system and the room and that isolation is either not possible or ineffective. Are you aware of Michael Green and are your methods similar to his?
