RE: Gatorboard / Gatorfoam Revisited

Thanks, Duster. In fact, I did some experiments with these exact discs -- having ordered a bunch when you first introduced them. Sonically, they didn't seem either beneficial or detrimental when used this way. And that may have had everything to do with my turntable's pretty substantial suspension, which is comprised of four cartridges containing springs in silicone fluid.

But, these discs were far from ideal in that I was forced to use them in stacks of three due to an additional consideration: whatever I use to elevate this isolation platform must clear the 7/8" brass caps in the four corners of the top shelf of my audio rack. When stacked this way, the carbon fiber discs made the ~100 lbs. above seem precariously balanced. Especially when you factor into the equation a couple of acrobatic felines with whom I cohabitate. The fact is that excellent lateral stability would add a lot of comfort, even if it doesn't contribute much to (or even detracts a little from) sonics.

Duster, I know that you like the Herbie's Audio Lab products, and I wonder if something like the "Extra-Firm Big Tall Tenderfeet" might work, here? I've also come across something called "MagicHexa" from Agora Acoustics (link below). Here's a description:

The MagicHexa Audio Vibration Isolation damper feet are made from a proprietary visco elastic polymer that combines shock absorption, vibration isolation and damping characteristics to create the ideal acoustic damper and absorber. Its specially formulated Vibration Dissipating Aerodynamic honeycomb Configuration have almost 1,000 times higher damping coefficient than metal, thus reducing the transmission of various vibration energies into whatever surface the component is sitting on.

With respect to lateral stability, I wonder if the honeycomb design might serve to "suction" my maple boards together?

Anyway! Continued thoughts would be most appreciated!
