A test which used both under subs which had down facing ports worked against Townshend podiums which have an open center cut-out for their emblem. Maybe covering the emblem with something solid would have changed the results. Otherwise, Townshend's isolation is superior to Isoacoustics in my system (my neighbor lent me his Isocacoustic footers for several pieces of equipment). My Synergistic Research MigSx under amp and Stillpoints Ultra SS under pre-amp, isolation transformer, CD transport are better, soon (ordered) to be replaced by Townshend Platforms.
