Next-Gen Moving Magnet Phono Pickup

The apex of Sumiko's 3 new Oysters, Moonstone is dressed to impress. Further reducing moving-mass & output and topped off with 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 or confusion. Compatible with MM preamps and the vast majority of tonearms out there, Moonstone is a must-have for audiophiles on a budget.

The Latest Oysters

Designed for discerning, value-minded audiophiles, Rainier, Olympia & Moonstone supplement & complement the existing range of Oysters. They build upon, enhance, and 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 and instruments, as well as their attack and decay. Unique to these 3 Oysters (not to mention Amethyst), experience a diminutive backdrop that bolsters sonic images with a degree of aptitude reminiscent of moving coil designs.
