Product Details

Sumiko is excited to be introducing the the long-awaited RS 78 stylus for 78rpm discs! This stylus is interchangeable with each of our Next-Gen Oyster MM replacement styli — Rainier, Olympia & Moonstone — and it’s never been easier to switch over to shellac when you get the itch. It uses a 78-appropriate bonded 3mil spherical diamond with aluminum cantilever, tracks between 4.0 – 5.5g with a recommended VTF of 5.0g.

To be as clear as possible, what we’re offering here is only the replacement stylus (the yellow piece). It’s pictured both installed and uninstalled, but the 2nd image in the reel depicts what you’ll be getting when you order.


Considerations for 78rpm Records

Please note that it’s not advisable to play 78rpm records with a diamond stylus. Meant to track the ‘microgrooves’ of 33s & 45s, it will sound poor and cause undue harm to the disc (and potentially the cartridge!). Sumiko has developed RS 78 for this very reason. The stylus tracks the grooves properly and reduces the risk of harm to your collection. Keep in mind that Rainier, Olympia & Moonstone are stereo MM phono cartridges, meaning that their normal job is to transcribe 2 channels (left and right) of musical information. When using RS 78 with any of these cartridges, what you’ll hear is the one channel of musical information (mono) of the 78 in both stereo channels. For audiophile purposes as it pertains to 78s, a true mono cartridge with a 78-appropriate stylus delivers the best sonics.


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.

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.
