The AT33EV is a ½ inch, standard mount 0.3 x 0.7 mm elliptical cartridge featuring a tapered Duralumin cantilever which reduces the effective mass of the cartridge, resulting in a more durable cantilever. The Dual Moving Coil cartridge design increases channel separation and extends the frequency response range delivering extraordinary audio quality. Internally constructed with a neodymium magnet enhances magnetic energy and PCOCC wire for pure audio transmission.
Elliptical stylus chip and durable duralumin tapered pipe cantilever.
10Ω mid impedance specifications.
Dramatically increased magnetism with neodymium magnets and PCOCC as the coil.
High separation, wide-response Dual moving coil. 
VC mold eliminates unnecessary vibrations.
"Hanenite" anti-vibration rubber eliminates unwanted vibrations.
