- an improved engine, which provides a high level of sonic accuracy.
- R 18µm Nude Spherical diamond that is an optimal solution for playing mono microgroove LP vinyl records.
- the cartridge body is manufactured from Hopelex, an environment-friendly material which ensures high rigidity while eliminating unwanted resonances.
- 2M Mono uses a strapped output to deliver the same output signal from both sets of pole pins. This effectively eliminates the need for mono-specific equipment, making it possible to enjoy true mono reproduction on any stereo playback system.
The 2M Series provides excellent compatibility when used in an assortment of playback systems and with a wide variety of phono preamps.

"... the 2M Mono gave new cohesion to my listening experience...
...Having the Ortofon 2M Mono allows more closeness to these (MONO - red.) recordings...
Yes, stereo has won the ‘battle’ of recordings. It’s rare these days a label releases a mono version. However, the mono recordings have something interesting: in competing for space in a one channel sound, the various instruments create the ambiance of stillness, a hypnotic moment where all is there, the intensity of the moment in its full capacity. And here is where we can make the case that the 2M Mono from Ortofon gets you authentic and superior mono sound."

"...the 2M Mono is a truly exceptional transducer. The sound from this true-mono cartridge just blows away the sound you get from a mono-via-stereo cartridge setup. Because the mono cartridge only deals with the groove signal in a single plane, the resultant sound is impressively quiet compared to the modulation of surface noise and groove geometry shortcomings you often must deal with in playback of mono sources from a stereo cartridge. The end result is that you can really hear very deeply into the music; the 2M Mono sounded magnificent right out of the box, and has only gotten better as it's broken in.
...I would say that the 2M Mono has an up-front, somewhat forward quality in it's presentation of the music; the images are sharply detailed, but never etched—and the music is never fatiguing to listen to. This cartridge comes with my highest recommendation...
...with the very reasonable, real-world asking price and remarkable performance of the baseline model, I don't see how it could get much better than this!"

OUTSTANDING - simply the best!
"...I found this cartridge to be a very well thought out design, that complements the sonic presentation of the conventional 2M Series with an ability to play older, and sometimes more worn records, in an exemplary manner..."
- Last, quite punchy sound
- Very low surface noise
- Good detail retrieval
... The nude, spherical, 18 micrometer radius stylus is claimed by the manufacturers to be the optimum size for tracking the wider grooves of mono era records. It rides correctly in the groove, avoiding dirt at the bottom, unlike a smal/er microgroove stylus that rides too low..."
