Ortofon 2M Bronze Moving Magnet Cartridge

Overview

An elliptical stylus tracks a groove well, but its contact area is still large enough to miss some of the finest high-frequency detail cut into a record, especially toward the end of a side where groove speed drops.

The Ortofon 2M Bronze is a moving magnet phono cartridge built around a nude-mounted Fine Line diamond stylus, a narrower profile than the elliptical styli used lower in the 2M line that increases contact area with the groove wall and helps retrieve more high-frequency detail, particularly toward the inner grooves of a record. An aluminium cantilever keeps the stylus assembly light and rigid.

Output is rated at 5mV with 26dB of channel separation at 1kHz, and a lower recommended tracking force of 1.5 grams reduces wear on records over repeated plays. It's built to run into a standard 47kOhm phono input with 150 to 300pF of load capacitance, and it mounts to any standard half-inch headshell.

Simcoe Audio Video Insight

Because the 2M Bronze tracks at a lower recommended force than the 2M Red or 2M Blue, it's worth double-checking your tonearm's counterweight and anti-skate settings when installing it, since a setup dialed in for a heavier tracking cartridge won't automatically carry over.

Why the Ortofon 2M Bronze Stands Out

Nude Fine Line Stylus

A narrower profile than an elliptical stylus increases contact area with the groove wall for more high-frequency detail retrieval.

Higher Dynamic Compliance

Rated at 22µm/mN, suited to medium-mass tonearms.

26dB Channel Separation

Delivers more precise stereo imaging than the elliptical models lower in the 2M line.

1.5g Recommended Tracking Force

A lighter tracking force than the Red or Blue, helping reduce record wear over time.

Aluminium Cantilever

Keeps the stylus assembly light and rigid for accurate tracking.

Standard Half-Inch Mount

Fits any standard half-inch headshell without an adapter.

Buyer's Guide

Who It's For

  • The Detail-Oriented Listener: wants to hear more of what's cut into the inner grooves of a record than an elliptical stylus retrieves.
  • The Record Collector: values the Bronze's lower tracking force to reduce wear on records played repeatedly.
  • The 2M Blue Owner Considering a Step Up: wants a clear jump in stylus technology within the same cartridge family.

How It Compares

Where the 2M Blue's nude elliptical stylus improves on the 2M Red's standard elliptical, the 2M Bronze moves to a nude Fine Line profile entirely, widening the stylus's contact area with the groove wall for even more detail retrieval and a step up in channel separation to 26dB from the Blue's 25dB. The Bronze's recommended tracking force also drops to 1.5 grams from 1.8 grams on the Red and Blue, so its tonearm setup needs its own dial-in rather than reusing settings from lower models.

Ortofon 2M Bronze Moving Magnet Cartridge FAQs

What makes the 2M Bronze's stylus different from the 2M Blue's?

The 2M Bronze uses a nude Fine Line stylus rather than the Blue's nude elliptical, a narrower profile that increases contact area with the groove wall for more high-frequency detail, especially toward the inner grooves of a record.

Does the 2M Bronze need different tonearm settings than the 2M Red or 2M Blue?

Yes. It's rated for a lower 1.5 gram tracking force compared to 1.8 grams on the Red and Blue, so counterweight and anti-skate need their own adjustment rather than reusing settings from those models.

Will the 2M Bronze fit my tonearm?

Yes. It mounts to any standard half-inch headshell, the same mount used across most of Ortofon's 2M line.

What output voltage does the 2M Bronze produce?

It outputs 5mV at 1kHz, compatible with the standard 47kOhm input found on most moving magnet phono stages.
