A lightweight round needle MM type cartridge for all record listeners.
Ortofon's OM series, which has a unique design shape, has its roots in the Concorde series, which was released in 1979 with an integrated headshell, and the LM series, which can be attached to the headshell.
These products were born in the midst of the trend toward lighter mass and lighter stylus force, which many cartridge manufacturers were enthusiastically working on at the time, and the LM series, which achieved an ultra-light body with a body weight of 2.6g, was the decisive blow.
Many of the products that were said to be lightweight at the same time had a weight of around 5g, so the LM series can be said to be a cartridge that embodied the ideal of "Lomas" at the time.
Subsequently, the OM series housing was created with the development of the MC-type lightweight model MC200 Universal, which is even lighter than the LM series, weighing 2.5g, and by attaching an insertable and removable 2.5g brass extra weight (described later), the cartridge weight was reduced to 5g, making it versatile for use with tonearms that are not exclusive to lightweight cartridges.
The OM 5 series of MM cartridges, which most closely inherit the genealogy of Lomas cartridges, is led by the Super OM 5E (elliptical needle), which bears the name "Super", and is the only model in the series to use high-grade housing materials and magnetic circuits, regardless of cost.
On the other hand, the lineup consists of three models, including entry models OM 5E (elliptical needle) and OM 5S (circular needle), which maintain performance through the same basic design philosophy and offer excellent cost performance.
This series boasts optimal performance as a cartridge for not only audiophiles who are interested in Hi-Fi, but also record listeners who love vinyl records to immerse themselves in the music.
