ORTOFON 2M Black Cartridge
from http://www.
positive-feedback.com/Issue39/ortofon2m.htm :
"The 2M series is available in four different iterations, which are divided into two tiers. The 2M Red ($99) and Blue ($199) share the same plastic cartridge body and engine, but where the Red uses a standard ellipitical stylus, the Blue employs a polished, nude ellipitcal diamond. The second tier is comprised of the Bronze ($389) and Black ($669), which share an advanced Noryl/glass composite body and a more sophisticated engine. The Bronze sports a nude fine-line diamond, while the Black has a top-of-the-line Shibata profile. Both the Bronze and Black also use silver-plated wire internally instead of copper. Styli are interchangeable within both tiers, so the buyer of a Red can cost-effectively upgrade to Blue for only the price of the stylus unit. Ditto with the Bronze and Black."
From Ortofon:
2M Black - The 2M series were developed in conjunction with Danish designer Møller Jensen Design – the same designer who designed the award winning MC Jubilee and 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.
2M are designed for precise and accurate retrieval of the information in the record groove. Our philosophy is to play the record sound as accurate as possible, without coloring the sound. We have optimized the design for ease of mounting the cartridge, weight and size to fit the most common turntables at the market today.

The name 2M was selected among several ideas. We wanted a modernname which should be easy to pronounce and to remember, and therefore an alpha numerical name was chosen. 2M means MM, which is the abbreviation for moving magnet.
The 2M Black is the new moving magnet flagship from Ortofon. The 2M black is graced with a Shibata diamond stylus – the same diamond as on the acclaimed MC Jubilee. Its slim, highly polished profile allows an exceedingly wide contact area to the groove walls and ensures notably detailed reproduction throughout the spectrum, including even the most high frequency groove information. Users of the 2M Black will enjoy the benefit of impeccable sound quality, along with reduced record & stylus wear and reduced distortion and phase error as a result of the diamond’s improved tracking geometry.
The cartridge body used for the 2M Black is manufactured from a newly-developed Noryl plastic/glass combination, a revolutionary material which ensures high rigidity while eliminating unwanted resonances. The 2M Black uses a special upgraded engine, featuring split pole pins with a silver plated copper wire.
