Audio Technica AT-ART9XI

Featuring a special line contact stylus on a 0.28 mm diameter solid boron cantilever, the Audio Technica 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.

Why So Many Styli Shapes?

The purpose of a stylus is to ride along the record groove capturing movement, which is then transferred into an electrical signal within the turntable cartridge. Audio-Technica produces styli in five different shapes (Conical, Elliptical, Microlinear, Shibata, and Special Line Contact) that make contact with the record groove and capture movement in different ways, creating unique sound characteristics.

Special Line Contact Styli

The special line contact stylus is shaped to track the record groove with the highest level of precision, resulting in excellent high-frequency response, low distortion and minimum abrasion. The special line contact stylus makes more surface contact than any other stylus shape.

It should be noted that due to its high-fidelity, the line contact stylus may produce more noise on heavily worn records. The line contact tip is used on our higher-end cartridges.
