The differences among the 2M variants concern two primary areas: engine and stylus profile. The entire 2M Series features Ortofon’s trademark split pole pins, an invention which enables moving magnet cartridges to have a flat frequency response as with a moving coil cartridge. Split pole pins were invented by Ortofon, and were originally presented in the 500 and Ortofon OM Super Series. The 2M 78, 2M Mono, 2M Red and 2M Blue use an improved engine, which provides an optimized sound reproduction and a high level of sonic accuracy.
All of the 2M cartridges feature diamonds which are polished to the highest standards of the industry. The 2M Red features a bonded Elliptical diamond, while the 2M Blue features a Nude Elliptical diamond.
- an improved engine, which provides an increased output of 5.5 mV and an optimized sound reproduction and a high level of sonic accuracy.
- Nude Elliptical diamond and split pole pins with a copper wire.
- The cartridge body is manufactured from Hopelex, an environment-friendly material which ensures high rigidity while eliminating unwanted resonances.
We have optimized the design for ease of mounting the cartridge, and the weight and size to fit the most common turntables on the market today. The 2M Series provides excellent compatibility when used in an assortment of playback systems and with a wide variety of phono preamps.
The 2M Blue adds more dynamics and resolution, sounds more open and reproduces more details compared to the 2M Red model.
