Audio-Technica AT-OC9XEN Dual Moving Coil Cartridge with Nude Elliptical Stylus and Aluminum CantileverDual Moving Coil design, featuring independent coils for both left and right channels, provides outstanding channel separationThe coils are aligned in a reverse V-shaped formation, which exerts less pressure on the stylus, thereby minimizing distortionThe cartridge body is pre-threaded, enabling it to be mounted onto the headshell or integral tonearm with just two screws – no nuts requiredFeatures nude Shibata stylus and boron cantilever for rich full-range audio reproduction and high transient responseA neodymium magnet and permendur yoke provide dramatically increased magnetic energyAluminum body minimizes unwanted vibration for reduced resonance and superior audio reproductionPure Copper by Ohno Continuous Casting process (PCOCC) is used for the coils to achieve pure signal transfer
