Sumiko Amethyst

Oyster Series

The Oyster Series' premium Moving Magnet cartridge range features four models with a matching aesthetic, all named after a different type of Oyster.

The Amethyst is the flagship of the series, and easily SUMIKO's most ambitious moving magnet cartridge to date. Featuring a nude Line-Contact stylus coupled to a 0.5mm diameter aluminium cantilever, it's capable of extracting every minute detail from the record groove. Due to the level of fidelity on offer, the Amethyst also employs a mechnically enhanced body compared to the more affordable Rainier, Olympia and Moonstone models. With its unique body, the Amethyst's upgraded generator assembly provides ultra-low noise, hair-raising dynamics and superior tracking ability. This exceptional cartridge is so accomplished, it even surpasses some moving coil cartridges in resolution and detail.

The Amethyst looks the same as the other models in the series, but its body is unique, so it should only be fitted with the RS Amethyst replacement stylus.
