Rainier introduces our latest range of Oysters, which raise the bar for what can be expected from reasonably-priced MM cartridges. Our resonance-optimized housing was developed & selected for the voicing that it lends. The resonance properties create a well-represented soundstage with fantastic clarity with an overlaying warmth. Impressively quiet while delivering impact, Rainier skillfully places instruments & vocals right where they belong. You can expect a broader, rounder soundstage than you previously thought attainable at this price.

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.
