Enhanced motor for increased 5.5 mV output power and optimised sound reproduction with high levels of accuracy.
Elliptical diamond and split pole tips with copper wire.
The cartridge body is made of environmentally friendly Hopelex material which provides high rigidity while eliminating unwanted resonances.
We have optimised the design for ease of insert installation as well as weight and size to suit most popular turntables on the market today. The 2M range provides excellent compatibility when used in a range of playback systems and with a wide range of phono preamplifiers.

The 2M Red is a versatile cartridge that delivers an open, dynamic sound with a slight warmth.

2M Series styles 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

Replacement stylus unit - 2M Red (interchangeable with 2M Blue and 2M Silver)

Stylus life: with proper care, up to 1000 hours of stylus life is possible without degradation of performance.

Compatible with Rega TT / TA brand:

The height of REGA brand cartridges from the needle tip to the top surface of the cartridge mount is lower than standard. Therefore, spacers would be needed to ensure the correct alignment of the Ortofon cartridge.
Adjusting the height of the Rega tonearm is easy with the Acoustic Signature pad set. It allows height adjustment from 0.5mm to 3.5mm in precise 0.5mm increments - without removing the tonearm. Simply loosen the screws, insert the AS spacer, then lock the screws back in place and you have a ready to play tonearm.
The 3.2 - 4 mm spacers should be sufficient for a 2M cartridge.
