The OMP 10 is a magnetic cartridge (MM) with an elliptical shaped stylus that is a great foray into the world of HiFi, based off of the proven and time-tested OM series.
The P-mount OMP 10 has been designed for tonearms with T4P mounting sockets, the plug-in attachment system first introduced by Technics and adopted by Sony, JVC, Grundig and many other manufacturers.
The OMP model requires no change in mass for the simple reason, that its mass is precisely what is specified for tonearms with T4P mounts
