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:

Shibata Tip Profile 
Solid Boron Cantilever
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.
