RE: Gatorboard / Gatorfoam Revisited

Thanks, Duster! I think I get it: even one additional squishy layer is likely not to play well with my turntable's suspension; instead, you recommend that the suspension be the only compliant "layer" -- with everything else being rigid.

Would Herbie's "Hi-End Booster Bases," used in conjunction with the Grungebuster Dots (which I think you originally recommended), be an improvement over the Tenderfeet?

To your immediate suggestion, metal cones or spikes are certainly doable -- although that's not something I use and have around. If I were to start with what I have on hand, I could try either the old Polycrystal cones (lots of those around) or a set of Finite Elemente Ceraballs, which I'm thinking might conform to your suggestion:

Despite the employment of ball bearings, here, these devices don't shift horizontally like most bearings do. They're quite stationary. And as a result, I believe that they act very much like cones or spikes, with their functionality being almost entirely in the vertical coupling realm:

The CERA technology is based on direct coupling for effective transfer of sound interfering resonance. Fast resonance transfer is provided by extreme hard high-tech ceramic balls. Combined with precision machined materials like stainless steel or aluminum the optimum balance between damping and deflection is achieved. The resulting vacuum effect draws off unwanted resonance directly where it evolves.

Hmmm ... yea or nay? Could these be used alone, or should they be matched up -- top or bottom or both -- with the carbon fiber discs?

You know, it strikes me that, by adding this extra platform, I really don't stand to gain anything beneficial, and I've probably laid some traps for myself. Would shifting gears and looking for a way to raise the turntable, on its own, high enough to clear the top-shelf obstructions -- while directly coupling it to that same top shelf -- be the preferred approach?

This has gotten a bit too thorny for my limited insight/knowledge. Please know how much I appreciate the expertise!
