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.
