For Refined Palettes

Utilizing the same vibration system, neodymium magnet and permendur yoke as the AT-OC9/III MicroCoil™ cartridge, the AT-ART9 is designed to provide sound reproduction of the highest quality. The cartridge’s special line contact stylus, with a 40 µm × 7 µm curvature radius and a 0.26 mm diameter solid boron cantilever, enables an extremely accurate reading of the record groove and faithful transfer of the signal from the stylus tip to the magnetic coil. The VC mold design ensures stability and rigidity, while the dual moving coil (fashioned from high-performance PCOCC wire) offers excellent stereo separation and improved frequency response for long-lasting performance. The hybrid housing of machined aluminum and hard plastic, along with the machined aluminum base supporting the magnetic circuit and vibration system, reduces unwanted resonance and supports stable playback.

    Wow, what an improvement!


    I've had a Dynavector 10x5 for two years, and have put at least 1000 hours on it. Love it! But, then one sad day I bent the cantilever. So, off to NeedleDoctor for a replacement. My research led me to a few, and I chose the ART9 based on what I read and what Ken suggested.

    When he mounted it Ken said it may be his new favorite. Now I have run it in for about 15 hours and I can't believe the improvement over the Dyna! This is really just a "right" sound. It's open, natural, quiet. The bass is smooth and full, the highs are very natural and the response high to low is just so natural.

    It has really transformed the sound of my records. Where I thought the Dyna was good, this is so much better. Kudos to NeedleDoctor on another great recommendation and superb customer support!
