Dual Moving Coil Cartridge


The AT33Sa is the first Audio-Technica moving coil cartridge to feature a Shibata line-contact stylus, known for its superior high-range performance and strong mid and bass sound. The stylus is mounted on a tapered boron cantilever with a double damper for reduced weight and better audio quality.

The cartridge’s dual moving coils provide excellent channel separation and are affixed within a strong but lightweight VC mold to greatly reduce unwanted vibration.

The cartridge uses a neodymium magnet and a permendur yoke for dramatically enhanced magnetic energy.

The PCOCC (Pure Copper by Ohno Continuous Casting) coils ensure pure audio transmission.

    • Moving coil cartridge with Shibata stylus delivers exquisite, full-range audio reproduction


    • Advanced tapered boron cantilever and reduced coil weight improve the audio quality, particularly in the higher frequencies


    • Neodymium magnet and permendur yoke dramatically enhance the magnetic energy


    • PCOCC (Pure Copper by Ohno Continuous Casting) coil enables pure signal transfer


    • High-separation, wide response dual moving coil


    • VC mold limits unnecessary vibration


  • Precision-cast hard aluminum alloy body enhances rigidity and the signal-to-noise ratio
