An update of the AT-ART7, the Audio Technica AT-ART9XA non-magnetic core MC cartridge features a Shibata stylus on a 0.28 mm diameter solid boron cantilever.
The “ART” in the model number stands for Audio-Technica Reference Transducer, a designation that we give only to our flagship phono cartridges. Compared with the magnetic core used in most MC cartridges, non-magnetic core cartridges are free from magnetic distortion, allowing for natural timbre and a precise sound field. Although conventional non-magnetic cores struggle with output voltage, the AT-ART9XA features a newly designed coil armature with an improved output voltage of 0.2 mV (1 kHz, 5 cm/sec). The dual moving coils (fashioned from high-performance PCOCC wire) are aligned in an inverted V shape to provide high separation and wide response. Threaded cartridge mounting holes make installation to a headshell or integrated tonearm incredibly easy.

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.
The Shibata stylus was originally developed to play four-channel (quadraphonic) vinyl records. The Shibata stylus has two radii, similar to an elliptical stylus. However, the radii of a Shibata stylus allow for more surface contact and effective pickup of ultra-high frequencies with less groove stress and distortion.
