Audio Technica AT-ART9XA
Features
- Non-magnetic core moving coil cartridge offers superior spatial representation
- Dual moving coils are aligned in an inverted V shape, providing high separation and wide response for clear sound localization and minimal distortion
- Shibata stylus ensures accurate high and mid-low range reproduction, and the 0.28 mm diameter solid boron cantilever provides excellent response characteristics
- Neodymium magnet and permendur yoke significantly increase magnetic energy
- Redesigned coil armature provides an output voltage of 0.2 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

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.
Shibata Styli
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.
