AT-ART9XI

Featuring a special line contact stylus on a 0.28 mm diameter solid boron cantilever, the AT-ART9XI replaces the AT-ART9 as Audio-Technica’s flagship magnetic core MC cartridge.

The “ART” in the model number stands for Audio-Technica Reference Transducer, a designation that we give only to our flagship phono cartridges. The specially designed magnetic circuit boasts an output voltage of 0.5 mV (1 kHz, 5 cm/sec), making the cartridge easy to use and capable of reproducing even the most delicate expressions, while also ensuring dynamic playback. The dual moving coils (fashioned from high-performance PCOCC wire) are aligned in an inverted V shape to provide high separation and wide response for clear sound localization and minimal distortion. Threaded cartridge mounting holes make installation to a headshell or integrated tonearm incredibly easy.


Features

Audio-Technica’s flagship magnetic core moving coil cartridge

Dual moving coils are aligned in an inverted V shape, providing high separation and wide response for clear sound localization and minimal distortion

Special line contact stylus ensures faithful reproduction of the music signal, and the 0.28 mm diameter solid boron cantilever provides excellent response characteristics

Neodymium magnet and permendur yoke significantly increase magnetic energy

Specially designed magnetic circuit provides an output voltage of 0.5 mV (1 kHz, 5 cm/sec)

PCOCC coils ensure high-fidelity transmission

Machined aluminum base supports both the magnetic circuit and the vibration system, ensuring excellent playback stability

Hybrid body of machined aluminum and high-rigidity plastic reduces undesirable parasitic resonance

Threaded cartridge mounting holes allow easy installation to a headshell or integrated tonearm
