Ortofon was established in 1918 by Arnold Poulsen and Axel Petersen. It is a Danish manufacturing company of electronic audio equipment. With 500,000 cartridges sold annually, this became the world’s largest producer of magnetic cartridges for phonograph turntables. The company started focusing on sound film technology and began to diversify into gramophone record playback. They also pioneered the use of moving coil technology in phonograph equipment in 1945.

The AB model, Ortofon’s first moving oil magnetic cartridge, was launched in 1947. Due to demand from enthusiasts, the variations of this product are still manufactured today. In 1959, the first Stereo Pick-U SPU was introduced mainly for professionals. The versions of this device were being improved every year, for example, the 1992 SPU Meister and 2015 SPU Meister. During the 80th Ortofon’s Anniversary, the MC Jubilee was introduced. It was the company’s first time to use a metal housing manufactured with metal injection moulding.

In 2000, Johann Bach’s 250th death anniversary, The MC-Series “Kontrapunkt,” was invented. The models were named B, A, C, and H, wherein B has a ruby cantilever. Stainless steel was used for the frame of the housing. The 2009 Cadenza-series became of the successor of these pickups. Last year, 2019, the Anna Diamond was introduced to boasting its diamond cantilever.
