Replacement stylus for the Sumiko Wellfleet

Upgrade for MM cartridges

You can upgrade your Sumiko MM cartridge by simply replacing the stylus assembly. Important: all upgradeable cartridges operate at the same tracking force – therefore, no adjustments are necessary after a stylus upgrade.

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 the higher-quality stylus assembly: Lighter cantilever materials, a nude-mounted diamond, a diamond with a better cut, or a higher level of diamond polishing – aligned with or against the structure of the diamond crystal lattice – significantly improve sound quality.
