One of the preconditions for linear reproduction with a wide frequency range and optimal tracking performance is a diamond - the shape of which is as close as possible to the original cutting stylus. As in the entire Exclusives series cartridges, the MC A MONO makes use of Ortofon’s Replicant 100 diamond, known for its thin and light profile and extraordinarily large contact surface.

Since the Replicant 100 is closest to the shape of the cutting stylus, it can trace with accuracy unparalleled by any other needle in existence. Special polishing of the diamond, along with the use of a Boron cantilever, offer remarkable transparency, speed, and responsiveness beyond that of any other combination.

The magnet system is based on an extremely strong, compact neodymium magnet, which makes the generator system both compact and lighter through its minimal dimensions. Inspired by the elements of MC A95 design, the MC A MONO makes use of a specially designed armature comprised of a metal alloy which is much less magnetic than normal iron. This provides noteworthy benefit to the dynamic capabilities of the cartridge since the armature has almost no influence on the magnetic field during movement. When combined with the Aucurum coils, it delivers perfect reproduction of the cantilever movements without compromise.

Any trace of remaining magnetic influences that would create distortion is prevented by the use of a Field Stabilizing Element (FSE). Ortofon’s FSE, a small cylinder of conductive material strategically placed inside the magnet system, guarantees that the force field remains stable regardless of the movement of the armature. FSE improves the channel separation, while at the same time minimizing dynamic distortion and intermodulation.
