Upgrade of MM Cartridges
You can easily upgrade your Sumiko MM cartridge by replacing the stylus. Important: All upgradeable cartridges are operated with the same tracking force. After upgrading the stylus, no adjustments are necessary.
Advantages of a Higher-Quality Stylus Replacement:
Lighter stylus bodies, naked or better-cut diamonds, as well as improved polishing of the diamond—regardless of whether working against or with the structure of the diamond crystal lattice—significantly enhance sound quality.
