Machina Dynamica Super Stiff Springs (4) Cryo'd Isolators for heavy components set of 4

This auction for Machina Dynamica's brand new product - Super Stiff Springs for isolating very heavy components.  Four springs are offered in this auction, four springs are capable of supporting and isolating a heavy component weighing between 100-150 lb.   
Super Stiff Springs are just the ticket for heavy turntables like Verdier, Walker, and VPI, heavy amplifiers such as the big Classe and Lamm, and subwoofers.  To isolate lighter components use our Cryo Baby Promethean springs, 4 of which can isolate a component up to about 45 lb. All of our springs are cryogenically treated for optimum performance.  Typical resonant frequencies obtainable with our springs is around 3 Hz. In most case the springs can be placed directly under a component since the springs are very low profile and have inherently good lateral support (stability). The springs can also be used under suitable boards, I.e. Maple.
