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 Ohio continuous Casting) coils ensure pure audio transmission.
