Featuring a special line contact stylus on a 0.28 mm diameter solid boron cantilever the AT-ART9XI replaces the AT-ART9 as Audio-Technicas flagship magnetic core MC cartridge. The \"ART\" in the model number stands for Audio-Technica Reference Transducer a designation that they give only to their 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.
