Carbide Audio writes: “Introducing Carbide Base Sapphire. Carbide Base Sapphire is the result of our continuing research into ball bearing vibration isolators for audio. It sits between the award-winning standard and Diamond versions of the Carbide Base footer.
The difference from the Diamond version is the absence of our TwinDamp™ high-damping alloy and the bearing raceways that the bearings roll in.
The Sapphire raceways are formed from a hardened high-carbon steel. After 8 stages of polishing, the raceways are coated with a Diamond-Like Carbon (DLC) PVD coating combined with a special alloy. Finally, the raceways are cryogenic tempered to relieve internal stresses and improve toughness.
The result is an exceptionally hard, smooth, and low friction bearing rolling surface which is surpassed only by the PVD Diamond coated ceramic raceways on the Diamond version.
Carbide Base Sapphire is available for $399 USD each. The Sapphire Insert is available for $129 USD each to upgrade the standard version to the Sapphire version.”
