Sumiko Oyster Series Amethyst Moving Magnet Phono Cartridge

Outperforms Comparable Moving Coil Cartridges

The Amethyst is Sumiko's flagship Moving Magnet (MM) phono cartridge and requires its own unique cartridge body to maximize the performance of the excellent Nude Line Contact stylus. This exceptional cartridge even surpasses some moving coil cartridges in resolution and detail, setting a new benchmark for moving magnet cartridges with replaceable stylus assemblies.

Easily Sumiko's most ambitious moving-magnet (MM) cartridge to date, the Amethyst complements its nude line-contact stylus with an upgraded generator assembly providing ultra-low noise, breathtaking dynamics, and exceptional trackability. This unique setup takes advantage of the powerful electromotive forces inherent to MM cartridge designs that help give your playback some punch, while still outperforming most comparable moving-coil cartridges.
