Replacement stylus for the Sumiko Moonstone

MM cartridge upgrade

You can upgrade your Sumiko MM cartridge by simply replacing the stylus assembly. Important: all upgradeable cartridges operate with the same tracking force – therefore, no adjustment work is necessary after upgrading the stylus.

Since the Black Pearl and Pearl are identical except for the stylus, a Pearl stylus upgrades the Black Pearl to a Pearl. For the models from Rainier to Amethyst, the generators also differ. You can read details about the differences in this excellent report by Bernhard Rietschel from LowBeats magazine.

The advantages of a higher-quality stylus assembly: lighter cantilevers, a nude diamond, a better diamond cut, or a better polish of the diamond – against or with the structure of the diamond crystal lattice – significantly improve sound quality.

Stereo stylus upgrade steps

Rainier – simplest cantilever. Diamond with elliptical cut (r/R 8 x 18µm)

Moonstone – lighter aluminum cantilever. Diamond with elliptical cut (r/R 8 x 18µm)
