The 2M Blue is an upgrade from the Red. The 2M Blue uses the same structures but employs a highly polished nude-elliptical stylus for much better tracking and quieter reproduction, as it reaches deeper into the record’s grooves. The 2M Blue easily outperforms the older, more expensive and very popular OM-30!

The 2M series of cartridges feature Ortofon’s trademark split pole pins, an invention which enables moving magnet cartridges to have flat frequency response, just like a moving coil cartridge.  Ortofon invented the Split pole pin technology and were originally offered in the 500 series and Super OM series.

The 2M series was developed in conjunction with Danish designer Møller Jensen Design – the same designer who designed the award winning MC Jubilee and very successful Kontrapunkt series.  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. 

The 2M series is designed for precise and accurate retrieval of the information in the record groove. Ortofon's philosophy is to make cartridges which reproduce the record grooves as accurately as possible, without coloring the sound. The 2M series design has been optimized for ease of mounting and their weight and size fit virtually any current turntable. 

The name 2M was selected among several ideas. Ortofon wanted a modern name which would be both easy to pronounce and to remember, therefore an alpha numerical name was chosen. Mathematically 2M can be also represented as MM, which also happens to be the abbreviation for moving magnet.  Engineered to the highest standards the 2M series follows Ortofon’s unrelenting commitment to providing the most precise and accurate reproduction possible without coloration.
