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. Features 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 Specifications
