ORTOFON 2M Blue Cartridge
ORTOFON 2M Blue
:"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 elipitical stylus, the Blue employs a polished, nude elipitcal 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.
The 2M series were developed in conjunction with Danish designer MÃ¸ller Jensen Design â€“ 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 recordâ€™s surface, the 2Mâ€™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.
Of course the 2M isnâ€™t just another pretty face. It has been engineered to the highest standards and is congruent with Ortofonâ€™s unrelenting commitment to providing the most precise and accurate reproduction possible without coloration.
The 2M series of cartridges feature Ortofonâ€™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 series and Super OM series. The 2M Blue uses an improved engine, which provides an increased output of 5.5mV.
