The Story
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 their namesake Oysters dwell. They'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.
