Audio-Technica AT33MONO
AT33MONO
The AT33MONO is designed specifically for use with mono vinyl records.* Due to the horizontal configuration of its PCOCC (Pure Copper by Ohno Continuous Casting) voice coils, the AT33MONO cartridge only generates electrical signal with horizontal movement, yet it also has appropriate compliance in the vertical direction, making it safe for use with stereo records. The cartridge’s 0.65 mil conical stylus is mounted on a hard duralumin cantilever for excellent sound reproduction and dependable performance.
The AT33MONO is designed specifically for use with mono vinyl records.* Due to the horizontal configuration of its PCOCC (Pure Copper by Ohno Continuous Casting) voice coils, the AT33MONO cartridge only generates electrical signal with horizontal movement, yet it also has appropriate compliance in the vertical direction, making it safe for use with stereo records. The cartridge’s 0.65 mil conical stylus is mounted on a hard duralumin cantilever for excellent sound reproduction and dependable performance.
Because the AT33MONO does not easily pick up unnecessary strain components from distorted or scratched records, it produces mono audio of a much higher quality than that generated by a stereo cartridge. The cartridge features a strong, rigid body and incorporates Hanenite rubber in the interior and cantilever fulcrum support to eliminate unnecessary vibrations.
* This cartridge with 0.6 mil conical stylus is not compatible with SP (standard play) shellac records. It is designed to play microgroove 33-1/3 and 45 RPM vinyl records.
Please Note: AT33MONO’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.

Built for mono devotees, the MC mono design gives records a cleaner, richer, more immediate sound, with lower noise and better vocal focus than stereo playback. Audiophilia Guest Post notes vivid, dimensional results, while surface wear and pops are handled with ease, making this a highly specialized cartridge that rewards a serious mono collection.
Pros
- Delivers a richer, more immediate mono presentation with clearer vocals and stronger musical presence.
- Reduces noise, pops, clicks, and distortion effectively, even on records with groove wear or surface scratches.
- Improves mono playback with wider apparent soundstage and better separation of instruments and voices.
- Offers strong value for a specialist cartridge, with the review calling it an absolute bargain.
&
Cons
- Requires a moving-coil-compatible phono stage or head amp, so it is not as simple to deploy as a typical plug-and-play cartridge.
Sound Quality
88/100
Weighted average of sub-criteria below.
Overall Sound
90/100
Reviewers describe the cartridge as immediately impressive, with the sound becoming "richer," more "warm and inviting," and notably more vivid than stereo playback on mono records. The comments consistently point to a lively, dimensional presentation that makes familiar records feel more present and musically engaging.
Tracking Retrieval
87/100
The mono design is praised for reducing pops, clicks, distortion, and the noise floor, and for taking scratched records "beautifully in stride." That said, this is still a conical-stylus mono cartridge, so while the groove-reading and cleanliness are clearly strong, the evidence supports very good tracking rather than elite, top-tier retrieval claims.
Soundstage Imaging
80/100
As a mono cartridge, imaging is not the main point of the design, so this score is fixed at 80 per the scoring rules. The review language does suggest a wider, clearer, more dimensional presentation on mono records, but that improvement is best understood as a benefit of mono playback rather than stereo-style soundstage precision.
Show Less
Build Quality
85/100
The cartridge appears thoughtfully executed for its purpose, with a dedicated mono design and solid user-facing details such as the included accessories and conventional half-inch mounting. The reviews do not deeply dissect materials or workmanship, but nothing suggests weak construction or careless engineering.
Features Usability
83/100
Tonearm compatibility is reasonably good for a standard half-inch mount, and the cartridge should fit straightforward mono setups without unusual mounting issues. At the same time, it is a moving-coil design that requires compatible phono gain/loading and a bit more system matching than a typical plug-and-play MM cartridge, so usability is good rather than effortless.
The half-inch mount and moderate tracking force make it broadly usable, but the moving-coil output and required compatible input mean it is best suited to systems already set up for MC cartridges. That makes it practical for the intended audience, though not universally simple for all tonearms and phono stages.
Value for Money
96/100
At roughly $320-329, the reviews call it an "absolute bargain" and say it will deliver noticeable results and a marked improvement straight out of the box. That is unusually strong value language for this price class, especially given the clear enthusiasm for how much better mono records sound compared with stereo playback and other alternatives.
