Audio Technica AT-OC9XML Moving Coil Cartridge

Product Summary

The Audio-Technica AT-OC9XML is a premium dual moving coil phono cartridge designed for highly detailed, accurate vinyl playback. Part of the acclaimed OC9X series, it combines advanced cartridge engineering with high-quality materials to deliver excellent channel separation, low distortion and a refined analogue presentation.

The cartridge features a nude MicroLine stylus mounted on a boron cantilever. This advanced stylus profile is designed to trace groove information with exceptional precision, helping reveal fine musical detail, strong transient response and reduced inner-groove distortion.

Audio-Technica’s dual moving coil generator uses independent left and right channel coils arranged in a reverse V formation. This design helps reduce stylus pressure while improving channel separation and stereo stability for a more open and focused soundstage.

A rigid aluminium body helps control unwanted resonance, while high-purity PCOCC coils, a neodymium magnet and a premium permendur yoke all contribute to clean signal transfer and high magnetic efficiency. Threaded mounting holes also make installation easier on standard headshells and tonearms.
