The Pro-Ject 9cc is a precision 9-inch tonearm crafted from carbon fiber, designed to enhance the performance of turntables. It features a single-piece carbon-fiber headshell and armtube, which helps in reducing standing wave reflections, ensuring optimal sound quality. The design effectively channels parasitic vibrations away from the cartridge into the mounting board, facilitating accurate tracing of the record grooves. Its innovative inverted bearing design utilizes four ABEC7 spec ball races, while the solid ring type arm bearing housing minimizes resonances. The counterweight is uniquely designed to counteract unwanted resonances, and its lower positioning helps reduce dynamic wow and cantilever forces during playback. The tonearm allows for precise adjustments in vertical tracing angle (VTA) and needle azimuth with a single-screw fixing for easy rotation. The internal wiring is made from flexible, high-purity copper, ensuring high-quality signal transmission. The tonearm is compatible with cartridges ranging in weight from 6g to upwards of 14g, depending on the counterweight used, making it versatile for various setups. Specifications include an effective length of 230 mm, effective mass of approximately 8.5g, and an overhang of 18 mm.
