Description
Audio-Technica AT33SA 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.
