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 AT-ART9XI has been designated an Audio-Technica Excellence Product, a recognition that identifies products that meet our highest standards of high-fidelity performance.  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
