Product Description
Material Difference
The AT33xMLB’s solid boron cantilever, which tapers toward the microlinear stylus tip for improved response, is linked with a firm suspension mechanism, slightly lowering the dynamic compliance. Two independent PCOCC coils are positioned at the cantilever’s fulcrum to ensure pure signal transmission for each channel.
Sound Body
Each AT33x Series cartridge body is constructed of three distinct materials – die-cast zinc, aluminum, and high-rigidity polymer – optimally arranged to reduce and disperse resonance across the cartridge body so that no frequency predominates during playback. Threaded holes are incorporated into the body for easy mounting.
Key Features
- AT33x Series dual moving coil stereo cartridge with microlinear nude stylus
- Offers highly detailed and delicate sound expression; ideal for use with records produced since the late 1970s and for classical recordings that feature a host of instruments
- Dual moving coil design, featuring independent left and right coils, provides outstanding channel separation
- PCOCC (Pure Copper by Ohno Continuous Casting) coils provide pure, smooth signal transmission
- Neodymium magnet and permendur yoke maximize energy efficiency for high-resolution, responsive playback
- Composite cartridge body (die-cast zinc, aluminum, and high-rigidity polymer) reduces resonance throughout the body for balanced, natural sound reproduction
- Highly rigid and dense die-cast zinc material is used at the base of the cartridge to suppress unwanted vibrations and improve the expressiveness of the mid-to-low frequency range
- Threaded mounting holes make it easier to mount the cartridge to a headshell, especially one integrated into a tonearm
- Microlinear nude stylus tracks the record groove with incredible accuracy, providing more nuanced sound reproduction than elliptical and conical styli
- Solid boron tapered cantilever quickly transmits vibrations from the record groove, ensuring accurate reproduction of dynamic musical passages
- Newly developed suspension mechanism and rubber damper design (with lower dynamic compliance than other A-T cartridges) enable the cartridge to be used with a variety of tonearms
- Double-step armature structure increases the rigidity of the cantilever for better resonance suppression
- Thick gold plating on the terminal pins reduces contact resistance and enhances sound quality
- Crafted and hand-finished by artisans in Japan
