Sumiko Moonstone Moving Magnet Cartridge

The apex of the three latest Oysters, Moonstone by Sumiko is dressed to impress.

Further reducing moving-mass and output, and topped off with Sumiko's listen-tested 0.3 x 0.7 mil 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 with neither 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.

Sumiko Latest Oysters

Designed for discerning, value-minded audiophiles, Rainier, Olympia and Moonstone supplement & complement the existing range of Sumiko Oysters.

They build upon, enhance & refine the sonic character that listeners worldwide have enjoyed for decades. New innovation in cartridge design addresses the problem of resonance — the things that need to happen around a generator to voice a cartridge with honesty.

The housing thusly disperses & dissipates resonance, making way for effortless, transparent sonics that are enlivened with intimate nuance. The voicing is true to natural harmonics, space around voices & instruments as well as their attack & decay. Unique to these latest Oysters (not to mention Amethyst), experience a diminutive backdrop that bolsters sonic images with a degree of aptitude reminiscent of moving coil designs.
