SKU: OR-2M78
The 2M Series of cartridges is 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.

The name 2M was selected among several ideas. We wanted a modern name that would 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 series of cartridges feature Ortofon’s trademark split pole pins, an invention that 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.

We have optimized the design for ease of mounting the cartridge, weight and size to fit the most common turntables at the market today. 2M Series provides excellent compatibility in an assortment of playback systems and with a wide variety of phono preamps.

    Haven't tried it (yet) so perhaps I shouldn't judge.I'm planning to use either the "Blue" or "Bronze", and I'm sure to be quite pleased, but for all the heavier the 78 tracking weight specifies, it sounds TOO light to track a 78 with much authority. 4.5-6 grams would make more sense to me. I know the tip could take it, but I'm guessing the cantilever isn't designed to take that much weight-maybe I'm wrong..I guess I'll have to try it and see.
