Need a little help

For those of you who are actually by experience, familiar with both Symposium acoustics isolation system, mainly its Foundation rack, platforms, rollerblocks etc etc.. verses the Townshend seismic system, mainly the concept of pods under all components and/or seismic corners under the rack. If you are familiar with both and wouldn’t mind commenting on it, and sharing your experience and views with both, I would appreciate hearing it.
