Ortofon 2M Blue Moving Magnet Cartridge

Overview

A stylus bonded to a metal shank adds mass right where a cartridge needs to move the least, and that extra mass can round off the fine detail at the top end of a record.

The Ortofon 2M Blue is a moving magnet phono cartridge built around a nude-mounted elliptical diamond, removing the metal shank a bonded stylus relies on and reducing the moving mass at the stylus tip. Split pole pin technology helps keep the frequency response flat across the audible range, and an aluminium cantilever keeps the stylus assembly light without sacrificing rigidity.

Output is rated at 5.5mV with 25dB of channel separation at 1kHz, and it's built to run into a standard 47kOhm phono input with 150 to 300pF of load capacitance, covering the majority of moving magnet phono stages without extra adjustment. It mounts to any standard half-inch headshell.

Simcoe Audio Video Insight

Because the 2M Blue's nude stylus sits directly at the end of the cantilever without a metal mounting shank, it's more exposed to handling than a bonded stylus like the one on the 2M Red — worth keeping in mind when cleaning the stylus or setting tracking force for the first time.

Why the Ortofon 2M Blue Stands Out

Nude Elliptical Stylus

Removes the metal mounting shank a bonded stylus relies on, reducing moving mass at the tip for better high-frequency tracking.

Split Pole Pin Technology

Helps keep the frequency response flat across the audible range.

Aluminium Cantilever

Keeps the stylus assembly light without sacrificing rigidity.

25dB Channel Separation

Delivers more precise stereo imaging than a standard elliptical cartridge.

Wide Phono Stage Compatibility

Runs into a standard 47kOhm input with 150 to 300pF of load capacitance, covering most moving magnet phono stages.

Standard Half-Inch Mount

Fits any standard half-inch headshell without an adapter.

Buyer's Guide

Who It's For

  • The Detail-Focused Listener: wants the extended high-frequency tracking a nude stylus offers over Ortofon's entry-level cartridges.
  • The 2M Red Owner Ready to Upgrade: wants a clear step up in channel separation and stylus design without leaving the 2M family or changing phono stage settings.
  • The Hands-On Vinyl Enthusiast: comfortable with the extra care a nude stylus calls for during cleaning and setup, in exchange for its performance benefit.

How It Compares

Where the 2M Red uses a standard elliptical stylus, the 2M Blue steps up to a nude-mounted elliptical diamond, which Ortofon credits for its wider channel separation of 25dB against the Red's 22dB and a tighter frequency response tolerance. Both share the same 5.5mV output and 1.8g recommended tracking force, so the 2M Blue is a direct upgrade path for a 2M Red owner rather than a change in setup.

Ortofon 2M Blue Moving Magnet Cartridge FAQs

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

The 2M Blue uses a nude-mounted elliptical diamond rather than the Red's standard elliptical stylus, removing the metal mounting shank and reducing moving mass at the tip for better high-frequency tracking.

Will the 2M Blue 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 Blue produce?

It outputs 5.5mV at 1kHz, matching the standard input level most moving magnet phono stages expect.

Does the 2M Blue need special care because of its nude stylus?

A nude-mounted stylus is more exposed than a bonded one, so it's worth being a bit more careful when cleaning the stylus or handling the cartridge during setup.
