Borrowing from and refining on the resonance-optimized housing of our latest Oyster cartridges (Moonstone, Olympia & Rainier), we further reduce output to curtail extraneous noise. Topped off with a nude line-contact diamond, the stylus couldn’t be more nimble. Reaching every nook & cranny of your record grooves and handling that information with the utmost grace, Amethyst competes favorably with similarly priced MC designs. It’s shockingly quiet and thus transparent as can be, skillfully tracing even the most complicated passages your LP collection has to offer. Expect effortless dynamic handling, depth and clarity over a black background, impeccably realistic transience and images that leap from your soundstage but remain naturally positioned.


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.
