The AT33Sa is the first Audio-Technica MC cartridge model to feature a Shibata stylus. In addition to its superior high-range performance as a line-contact stylus, the Shibata stylus produces mid and bass sound that is strong and rich. The Shibata stylus is mounted on a boron cantilever with a double damper to greatly improve sound quality.

Advanced Tapered Boron Cantilever & Reduced Weight
The AT33Sa uses a tapered boron cantilever. Tapering the cantilever and revising the number of coil rotations reduce the weight, giving the cartridge better high range performance and wide range reproduction.
Neodymium Magnet & Permendur Yoke
The model uses a neodymium magnet with maximum energy product BHmax of 50 [kJ/m3] and a permendur yoke with high saturation flux density and outstanding magnetic properties, which further enhances the concentrated magnetic field of the coil gap.
Neodymium Magnet
The neodymium magnet provides maximum energy (BHmax of 50[kJ/m3]), while the pure iron yoke provides excellent magnetic properties. Together, they further boast the magnetic field concentrated in the coil gap area.
PCOCC Coil
The PCOCC coil enables purer transmission because it is not subject to grain boundaries in the direction of transmission. *PCOCC = Pure Copper by Ohno Continuous Casting process (Monocrystalline high-purity oxygen- free copper).
