Next-Gen Moving Magnet Phono Pickup

The apex of our 3 new Oysters, Moonstone is dressed to impress. Further reducing moving-mass & output and topped off with our listen-tested 0.3 x 0.7mil elliptical diamond, Moonstone transcribes sonic imagery with weight, richness, depth & sparkle. Texture is keenly realistic. The sonic image is suspended and well-controlled over a nearly-absent noise floor, providing fantastic clarity without etch nor confusion. Compatible with MM preamps and the vast majority of tonearms out there, Moonstone is a must-have for audiophiles on a budget.

Hand-Crafted in Japan

From Oyster to Reference, each Sumiko phono cartridge is crafted by hand in Yokohama, Japan — near the waters where our namesake Oysters dwell. We’ve selected by ear the finest materials that combine to deliver performance that has enlightened generations of listeners. Each design is thoroughly auditioned until perfected. Production is then executed by world-class cartridge makers with a collective eye for precision & quality. The result is a full horizon of cartridges eager to introduce themselves to your analog system — we firmly believe there’s a perfect cartridge for you here.
