The idea of hardness in decoupling is old as the hills and been used in audio circles for decades. The opposing view has held tenaciously to soft media that is compliant and decouples via absorption. Most of the methods today has or is migrating towards hardness as their preference. My own favorite and (relatively) cheap footers are the Symposium Acoustics HPDE Rollerblock Jr with tungsten balls used between hard anodized 7075 aluminum cups at +/- $100 per corner new. That puts the tungsten balls at 72HRC (Hardness on the Rockwell "C" scale) and the hard anodized aluminum oxide corundum cups at a Mohs scale of 9. In comparison zirconia can only manage an 8 on the same scale. Mohs scale is for crystelline minerals while Rockwell is for metal... no direct conversions available. Just thought one or a few might like to know.
Speaking of the hardness factor and footers I'm now wondering if placing a couple of my Rollerblocks under my D200 might now add even better/more enhancement than prior to anodizing since the hardness factor of corundum (Mos 9) has been added to the D200 belly pan and extending further up the decoupling chain. Will be interesting to find out some day in the not-too distant future.
But I'm absent from my prescribed duties and goal playing here... must get back to that now.
