Utilizing the same vibration system, neodymium magnet and permendur yoke as the AT-OC9/III MicroCoil cartridge, the AT-ART9 is designed to provide sound reproduction of the highest quality. The cartridge’s special line contact stylus, with a 40 µm × 7 µm curvature radius and a 0.26 mm diameter solid boron cantilever, enables an extremely accurate reading of the record groove and faithful transfer of the signal from the stylus tip to the magnetic coil. The VC mold design ensures stability and rigidity, while the dual moving coil (fashioned from high-performance PCOCC wire) offers excellent stereo separation and improved frequency response for long-lasting performance. The hybrid housing of machined aluminum and hard plastic, along with the machined aluminum base supporting the magnetic circuit and vibration system, reduces unwanted resonance and supports stable playback.
