Replacement stylus for playing 78 rpm records

MM cartridge upgrade

You can upgrade your Sumiko MM cartridge by simply swapping the stylus assembly. Important: all upgradeable cartridges operate with the same tracking force – so 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 very fine report by Bernhard Rietschel from LowBeats magazine.

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