The Sumiko RS Moonstone replacement stylus restores Moonstone performance or provides a direct upgrade for compatible Rainier-family cartridge bodies. Its narrower cantilever lowers moving mass, improving control, texture and the separation of closely spaced musical lines.
Compared with the less expensive RS Olympia, RS Moonstone retrieves more low-level detail, defines bass more precisely and holds images more securely during complex passages. It is the highest-value upgrade in the original Rainier–Olympia–Moonstone progression.
