The Sumiko Moonstone stands at the top of the new generation of Oyster cartridges, offering a refined, natural and highly detailed sound signature. With reduced moving mass, optimized output and a carefully selected 0.3 × 0.7 mil elliptical diamond, Moonstone delivers imaging with depth, richness and remarkable clarity over an exceptionally low noise floor. Its musicality and wide compatibility make it suitable for most tonearms and MM phono stages.
Its redesigned body has been engineered to minimize resonance, enabling a transparent and spacious presentation. Vocals and instruments appear with lifelike texture, precise definition and a natural decay, achieving performance reminiscent of premium moving-coil designs while maintaining full MM convenience. The result is a balanced, controlled and highly engaging listening experience.
The interchangeable stylus family—Rainier, Olympia, Moonstone, Wellfleet and Amethyst—provides a clear upgrade path. All styli are cross-compatible (with the Amethyst body being structurally unique), allowing listeners to tailor sonic preferences with ease. Hand-crafted in Yokohama, Japan, the Moonstone promises accuracy, reliability and long-term musical enjoyment.
