• Upgrading the MM cartridge

You can upgrade your Sumiko MM cartridge by simply replacing the stylus. Important: all upgradeable cartridges are operated with the same tracking force - so no adjustment work is necessary after upgrading the stylus. 

As the Black Pearl and Pearl are identical apart from the stylus, a Pearl stylus upgrades the Black Pearl to a Pearl. The generators also differ between the Rainier and Amethyst models. Details of the differences can be found in this very nice report by Bernhard Rietschel from LowBeats magazine.

The advantages of the higher-quality needle insert: Lighter needle carriers, a naked diamond or a diamond with a better cut or a better polish of the diamond - against or with the structure of the diamond crystal lattice - improve the sound quality considerably.
