Japan-based DS Audio introduced at CES 2017 its latest optical cartridge design, the DS002 at an attractive $5000 price point. The DS002 places the optical sensor in front of the elastomer suspension, which should produce faster response analogous to Audio-Technica’s ART1000 cartridge that puts the coils on top of the stylus (not that there’s really an comparison to be made between a coil and magnet based generator and one that uses an LED and optical shutter to generate a voltage).
