Ortofon 2M Mono Moving Magnet Cartridge
"...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 its 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!"

2M Series styli interchangeability:
The 2M Series' engines, coils, and magnets configurations are not identical: Red and Blue are identical, so are the Bronze and Black and so are the true mono variants 2M Mono and 2M 78. Likewise, 2M series styli are interchangeable within the below combinations:
- 2M Red, 2M Blue, and 2M Silver
- 2M Bronze and 2M Black
- 2M Mono and 2M 78
