Audio-Technica AT-OC9XSL

The next generation of the legendary OC9 capsule series

Since its launch more than 30 years ago, the pioneering OC9 series of moving coil capsules from Audio-Technica has won accolades from discerning vinyl listeners and professional reviewers alike for its musical transparency, expressive sound and precise construction. Special Line Contact featured in our flagship ART1000, this diamond profile offers the ultimate in precise sonic reproduction with a sense of space and realism for all instruments that few other configurations can achieve.

• It incorporates a Special Line Contact bare stylus and boron cantilever with precise tracking capability and high transient response.
  
• A neodymium magnet and permendur yoke provide a dramatic increase in magnetic energy.
  
• Threaded inserts in the capsule body allow the capsule to be mounted on the head or integrated arm with only two screws, no nuts are required
  
• Aluminium body minimises unwanted vibration for reduced resonance and superior audio reproduction
  
• Pure oxygen-free, continuous-cast copper (PCOCC) is used so that the coils achieve the purest possible signal
