Ortofon - Diamant Stylus Elektro

What is a cartridge?
It is an electromechanical assembly composed of a moving part (the stylus and cantilever assembly) and a fixed part (the pole pieces). There are two operating principles: moving magnet cartridges and moving coil cartridges. In the latter, unlike the moving magnet principle, it is the cantilever that carries a tiny coil that oscillates according to the groove between magnets, giving rise to the audio signal. The vast majority of cartridges used by professionals (DJs in particular) are of the “moving magnet” type because they offer greater robustness and allow easy exchange of the diamond. Moving coil cartridges are especially popular with audiophiles because they offer superior response linearity and an extremely low distortion rate.

Why different diamond profiles?
The theoretical profile of the stylus must be as close as possible to that of the engraving chisel to follow the groove in exactly the same way. This is impossible because this type of tip would leave a vinyl shaving behind it... So the stylus tip was given an elliptical profile that resembles the shape of an engraving chisel. The “Fine Line” profile, developed by Ortofon, further increases this similarity. An elliptical or Fine Line profile allows: better tracking of the finest undulations in the groove (corresponding to the finest sound details), a reduction in the pinching effect. Their larger contact surface ensures both better reading and less wear on the sides of the groove: the pressure per cm2 is lower with an elliptical or Fine Line tip than with a spherical tip.

In summary:
A spherical tip is particularly suited to Scratching.
An elliptical tip will prove universal, suitable for both scratching and playing musical tracks.
The Fine Line tip and other sophisticated profiles are reserved for HiFi use.
