The Ortofon Exclusives series has now been expanded to include the new MC A MONO, TRUE MONO cartridge model.


The MC Anna Diamond model represents the highest echelon of Moving Coil cartridges.
As its name suggests, the MC Anna Diamond uses a Diamond cantilever that in combination with Ortofon Replicant 100 diamond offers extreme transparency, speed and responsiveness beyond that of any other combination.

This state of the art product, representative of numerous Ortofon design elements and ideals, is truly exemplary of the highest degree of performance possible in contemporary analogue playback technology.

High-end materials

The housing of the cartridge is made of Titanium, using our famed SLM manufacturing technique which was pioneered by Ortofon during the manufacturing of the MC A90, Xpression, SPU A90, MC Anna and SPU A95 cartridges.

Considered an engineering breakthrough, the Selective Laser Melting process welds fine particles of Titanium together, layer-by-layer, to construct a single piece body devoid of extraneous material. This technique allows for precise control of the density of the body material, allowing for extremely high internal damping. The final result provides freedom over vibrations within the cartridge body material.

The use of Titanium has provided a further improvement to the internal damping capabilities as well as to the overall rigidity of the structure.

Extremely high-end materials benefit new coil technology

Using Ortofon’s Aucurum coils of gold-plated, 6NX oxygen free copper allows for zero-loss transmission of the diamond’s movements via its boron cantilever. This combination, which has also been employed for use in the MC Windfeld and MC A90 cartridges, combines low moving mass with an extremely high degree of rigidity.

A specially designed armature is used to achieve extreme precision in each coil turn in all layers. This enables the MC A MONO to achieve a higher degree of channel separation, while simultaneously offering lower distortion and better channel balance. The armature is made in a metal alloy which is much less magnetic than normal iron, which boosts the dynamic capability of the cartridge.

Coil wire protection has been constructed from our special high damping proprietary TPE (Thermo-Plastic Elastomer) material, which enhances the total damping properties of the cartridge.

The magnet system

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. The reason for this is that our high-tech armature has almost no influence on the magnetic field during movement. Hence when combined with the Aucurum coils of gold-plated 6NX oxygen free copper, 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.

The result: fantastic dynamics and even more elbow room between the musicians. You simply experience more drama and greater breadth, height and depth in the sound scenario.

Enhanced damping capabilities

Adding to the list of important components is Ortofon’s Wide Range Damping (WRD) system.

In this system, a small, heavy platinum disc is sandwiched between two rubber absorbers, both with different properties. This ensures not only an exceptional tracking performance, but also creates a perfect damping through the entire frequency spectrum. Because of this, distortion and resonance are virtually eliminated entirely.

The WRD system, which was originally introduced in the MC 20 Mk II in 1979 and was also used in the MC A90, MC Windfeld, Xpression and MC Anna phono cartridges, is one significant reason why the MC A95, while achieving the most linear frequency response and the highest upper frequency limit ever, at the same time tracks a fantastic 90 μm at a vertical tracking force of 2.3 grams.

Ortofon Replicant 100 - the finest diamond in the world

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 former the MC A90, MC Windfeld, Xpression and MC Anna cartridges, the MC A95 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.

Set-up and alignment

In order to attain maximum channel separation, it may be possible to adjust the azimuth. Should the cartridge not be perfectly perpendicular to the record’s surface, the tonearm or headshell may require to be tilted a few degrees.

Correct azimuth is established by observing the reflected image of the 2 parallel cartridge front lines. The cartridge’s front lines must form a straight line with the reflected lines. A flat mirror may also be used to facilitate this process.

There are 4 sets of screws included for mounting the cartridge to your tonearm. It is of great importance to choose the correct length of screws when mounting the cartridge.  Using too long screws may stop the screws inside the cartridge resulting in insufficient mounting in the headshell. The choice of screw length depends on the thickness of the headshell, and a maximum of 2.5mm free screw length under the headshell.
Mount the cartridge loosely to the headshell during this procedure.

Performance with a range of compatibility

With optimal weight and compliance to suit the vast majority of modern tonearms, the MC A MONO is easily compatible with a seemingly endless array of modern contemporary high-end turntable equipment.

Low internal impedance makes the MC A MONO less sensitive to load and therefore ensures compatibility with the Ortofon ST-80 SE transformer, as well as with the widest range of preamps and transformers.

By combining the utilization of the SLM process, our patented WRD system and zero-resonance spikes, we are confident that the perfect mechanical integration of this cartridge with your tonearm will result in a significant and breathtaking increase in dynamics, resolution, and richness in detail.
