Audio-Technica AT-OC9XEN

The AT-OC9XEN is a premium moving coil phono cartridge with a 0.3 x 0.7 mil Elliptical Nude stylus.

The OC9X range features a new Dual Moving Coil structure, which enables the audio information in the record grooves to be separated to the left and right channels with pinpoint accuracy. This improved channel separation results in a more precise stereo image and wider frequency response. The moving coil wires in all OC9X Series cartridges are made from PCOCC (Pure Copper by Ohno Continuous Casting), for optimum signal purity.

The AT-OC9XEN’s transducer engine is mounted onto a rigid aluminium body to help reduce unwanted internal vibrations and maintain sonic clarity. The cartridge bodies are pre-threaded, enabling them to be easily mounted to a headshell or tonearm with just two screws (no mounting nuts for the screws are required). Each OC9X Series cartridge is supplied with mounting hardware, a stylus brush and other accessories.

Note: Thehifishop charges a flat rate of $30 to professionally fit and align your new cartridge.
