Audio-Technica Dual Moving Coil Cartridge AT-OC9XSL

The AT-OC9XSL Dual Moving Coil cartridge with special line contact stylus is designed to provide outstanding channel separation. The Pure Copper by Ohno Continuous Casting (PCOCC) coils ensure pure audio transmission and are aligned in a reverse V-shaped formation to exert less pressure on the stylus, thereby minimizing distortion. Audio quality is further enhanced by a rigid aluminum body that reduces resonance, a neodymium magnet and premium permendur yoke that dramatically increase the magnetic energy, and the nude special line contact stylus on a boron cantilever that tracks the record groove with ultimate accuracy, delivering rich, full-range audio and high transient response. The cartridge body has been pre-threaded, enabling it to be mounted to a headshell or integral tonearm with just two screws – no nuts required.
