Ortofon 2M Bronze Verso sound box
The 2M Bronze features a nude Fine Line diamond stylus, which is particularly suited for demanding applications. The slim profile of the Fine Line stylus will track even the highest frequency information, making it a must for discerning listeners. Additionally, its larger footprint ensures reduced distortion and record wear.
The cartridge body used for the 2M Bronze and 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 Bronze and 2M Black use a special upgraded engine, featuring split pole pins with a silver-plated copper wire.
The 2M technology
2M cartridges are designed for precise and accurate retrieval of the information in the record groove. Ortofon's philosophy is to play the recorded sound as accurately as possible, without coloring the sound in any way. Both the 2M Bronze and 2M Black have Diamonds which are cut and polished to the highest standards of the industry.
The 2M design has also been optimized for easy mounting on a tonearm; the weight and size of all 2M models is well-suited to fit the most common turntables on today's market.
The 2M Bronze and 2M Black also have interchangeable stylus units, and replacement styli are readily available in the UK.
About the unique 2M design
2M was developed by Ortofon in conjunction with "Møller Jensen Design" from Copenhagen, Denmark - the same designer who collaborated on the award-winning MC Jubilee cartridge, and the coveted Kontrapunkt series.
The inspiration for designing the 2M was related to the facets of the diamond - elegantly concentrating its contours against the grooves on the record surface.
The name 2M was selected among several ideas. Ortofon wanted a modern name which would be easy to pronounce around the world, and to remember. Therefore an alpha-numerical name was chosen...
2M means MM, which is simply the common abbreviation for Moving Magnet.
The 2M range has been structured in the same way as the popular Rondo and Cadenza Moving Coil series, with ascending quality as you move from Red - Blue - Bronze - Black. The Spectacular 2m Black has become the Flagship of 2M, and all Ortofon moving magnet cartridges.
2M was also the last product designed by Ortofon's former chief engineer, Per Windfield. He developed the 2M series over the final 2 years of his 30 year tenure with Ortofon.
