AT33xMLB Moving Coil Cartridge

The latest update to the venerable AT33 Series – the first extensive overhaul in years – brings new warmth and fullness to your favorite music. Incorporating technological and material improvements, including our first use of die-cast zinc at the base of the cartridge to ward off unwanted resonance and improve expressiveness in the mid to low frequencies, the AT33x Series cartridges let you hear the finest details across the audio spectrum.

With its microlinear nude stylus and solid boron tapered cantilever, the AT33xMLB is capable of capturing the subtlest details cut into a record groove. This capacity for high-resolution tracking is particularly noticeable when listening to orchestral recordings, allowing you to discern each instrument on a piece, or when playing records made since the late 1970s, which benefit from high-fidelity recording and manufacturing advancements. Our newly developed suspension mechanism uses piano wire for even better tracking accuracy, lowering the dynamic compliance slightly for more substantial audio, particularly in the mid-low range.

 

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

Please Note: AT33xMLB’s stylus assembly is not field-replaceable, but Audio-Technica offers a fee-based Moving Coil Exchange Program to properly service your moving coil cartridge.
