Spikes are clearly acoustical couplers (that’s why you want them on the bottom of your speakers), so why would I want to couple the upper platform to my TT you may ask?…  Well, by doing so I effectively increase the mass of my TT plinth by 9 pounds whilst the entire thing is isolated.  And, by virtue of their design they act as mechanical diodes (one way valves) to remove any mechanical vibrations from my TT motor away from my stylus (page 406).

The acoustic adventures continue…
