Audio-Technica AT-OC9XML Moving Coil Cartridge

The AT-OC9XML Dual Moving Coil cartridge with Microlinear 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 increase the magnetic energy. The nude Microlinear stylus on a boron cantilever tracks the record groove with incredible accuracy, low distortion, 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.
