Flagship magnetic-core moving coil cartridge • Nude Special Line Contact (SLC) diamond stylus • 0.28 mm solid boron cantilever • Dual Moving Coil (MC) structure with PCOCC wiring • Machined aluminum and high-rigidity polymer hybrid body • Integrated threaded M2.6 mounting holes
The Audio-Technica AT-ART9XI Dual Moving Coil Cartridge serves as the premier magnetic-core flagship in Audio-Technica’s reference ART Series, engineered for immense dynamic impact, expansive soundstaging, and microscopic groove resolution. Featuring a redesigned magnetic circuit incorporating a high-permeability magnetic core armature and neodymium magnets, it produces a robust 0.5 mV output that delivers energetic transient slam and effortless low-end drive. A precision-cut nude Special Line Contact diamond paired with an ultra-rigid 0.28 mm solid boron cantilever extracts high-frequency detail without distortion, while an inverted V-shaped coil structure and hybrid resonance-damped aluminum chassis ensure pure, three-dimensional analog playback.
Key Features & Innovations
Advanced magnetic-core armature — employs an optimized magnetic core architecture that dramatically boosts electromagnetic conversion efficiency, delivering high dynamic expression and a healthy 0.5 mV output.
Special Line Contact (SLC) nude diamond stylus — precision-polished line-contact profile offers broad vertical groove contact, providing rich harmonic retrieval, sweet high-frequency extension, and minimal record wear.
0.28 mm solid boron cantilever — stepped, ultra-slender boron rod delivers high rigidity with low moving mass, transmitting groove modulations with instantaneous transient speed.
Hybrid anti-resonance chassis — precision-machined aluminum base plate combined with a high-rigidity polymer housing disperses parasitic resonances, while integrated M2.6 threaded holes permit clean top-down mounting without loose nuts.
PCOCC coil wiring in inverted V-shape — wound with ultra-high-purity Pure Copper by Ohno Continuous Casting (PCOCC) conductors in a reverse V-geometry to maximize stereo separation and lower crosstalk.
High-energy neodymium magnet system — optimizes the magnetic gap flux to ensure wide frequency linearity spanning 15 Hz to 50,000 Hz.
The Audio-Technica AT-ART9XI uses a magnetic core armature with a Special Line Contact stylus, producing a higher output of 0.5 mV along with tremendous dynamic punch, bass authority, and slam. In contrast, the sibling AT-ART9XA uses a non-magnetic core (air-core) armature with a Shibata stylus, generating a lower output of 0.2 mV with an emphasis on sheer spatial transparency and midrange delicacy.
What phono preamplifier gain and loading settings are recommended?
With an output voltage of 0.5 mV, the AT-ART9XI works exceptionally well with standard Moving Coil phono stages providing around 56 dB to 62 dB of gain. The recommended load impedance is 100 ohms or greater (or around 20 ohms with a step-up transformer).
What is the recommended vertical tracking force (VTF)?
The recommended vertical tracking force is 1.8 grams, with an acceptable operational range of 1.6 to 2.0 grams.
Can I install this cartridge without holding small nuts underneath?
Yes. The body incorporates threaded M2.6 brass inserts, allowing direct top-down installation into any standard 1/2"-mount headshell using only the provided M2.6 screws.
