Unreal Summary
What We Like
The 2M Series was developed in conjunction with the Danish designer Moeller Jensen Design. Inspired by the facets of a diamond, whose contours gracefully trace the grooves on a record’s surface, the 2M’s handsome elegance establishes a great combination of form and functionality. Of course the 2M isn’t just another pretty face. It has been engineered to the highest standards and is congruent with Ortofon’s unrelenting commitment to providing the most precise and accurate reproduction possible without coloration. The name “2M” was chosen as it represents the abbreviation for moving magnet, MM.
Advancements in Sound
The differences among the 2M variants concern three primary areas: engine, body material 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 Red and 2M Blue use an improved engine, which provides an optimized sound reproduction and a high level of sonic accuracy.
Styli Types
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.
Styli Interchangeability
2M Series styli are engineered for a tight fit to minimize coupled vibrations, thereby improving sound reproduction. Physically 2M styli will fit on alternative 2M cartridges bodies, but 2M Series cartridges’ engines, coils and magnets configurations are not quite identical: Red and Blue are identical, and so are the Bronze and Black.
