The Next Generation of the Legendary OC9 Series of Capsules

Since its launch more than 30 years ago, Audio-Technica's pioneering OC9 series of moving coil capsules has been recognized by both discerning vinyl listeners and professional critics for its musical transparency, its expressive sound and precise construction. Special Line Contact featured on our ART1000 flagship, this diamond profile offers the ultimate in accurate sonic reproduction with a sense of space and realism for all instruments that few other setups can achieve.

It incorporates a bare Special Line Contact needle and a boron cantilever with precise tracking and high transient response.

A neodymium magnet and permendur yoke provide a dramatic increase in magnetic energy.

Threaded inserts in the cartridge body allow the cartridge to be mounted to the headstock or integrated arm with just two screws, no nuts required

Aluminum body minimizes unwanted vibration to reduce resonance and audio reproduction superior

Continuously cast oxygen-free pure copper (PCOCC) is used for the coils to achieve the purest possible signal
