Ortofon Anna- The pinnacle in moving coil design
« on: November 02, 2019, 10:42:49 AM »
The MC Anna & MC Anna Diamond Moving Coil Cartridges

The Ortofon Exclusives series of our highestperforming Moving Coil cartridges has now
been expanded to include a new premier model:
the MC Anna Diamond.
As its name suggests, the MC Anna Diamond
uses a solid Diamond cantilever that in
combination with Ortofon Replicant 100
diamond offers extreme transparency, speed
and responsiveness beyond that of any other
combination. Both MC Anna and MC Anna Diamond models
represent the highest echelon of Moving Coil
cartridges. These state of the art products,
representative of numerous Ortofon design
elements and ideals, are truly exemplary of
the highest degree of performance possible in
contemporary analogue playback technology

The MC Anna and MC Anna Diamond
cartridges represent a landmark in
Ortofonís research and development
- The housing and the body of the cartridge are made in
Titanium with the Selective Laser Melting (SLM) technique.
The SLM technique was pioneered by Ortofon for
manufacturing of the MC A90 and the SPU A90 cartridges,
and was refi ned in subsequent Exclusive Series models.
- High-performance iron-cobalt alloy is applied for select parts
of the magnet system.
- The WRD armature damping system provides complete
elimination of unwanted resonance.
- The Ortofon Replicant 100 diamond, thin and light, with
an extraordinarily large contact surface, provides tracing
accuracy unparalleled by any other needle in existence.
- The MC Anna uses a Boron cantilever which is strong, stiff,
light and 100% inert.
- The MC Anna Diamond features a new Diamond cantilever
that ensures the best possible interface between the stylus
and the armature. It offers speed, fl uidity, and harmonic
reproduction beyond that of any other material. The use of
Diamond cantilever in the MC Anna Diamond has prompted a
paradigm shift in our understanding of analogue reproduction.
Benefi ts of high-end materials and
advancements in technology
An engineering feature adding to the damping capability of
the MC Anna and the MC Anna Diamond cartridges is the
SLM technique in which fi ne particles of Titanium are welded
together, layer-by-layer, to construct a single piece body devoid
of unnecessary material. Using this technique, the density of
the body can be precisely controlled, allowing for extremely
high internal damping. The fi nal result provides absolute
freedom from resonances existing in the cartridge body material
and allows for the MC Anna and the MC Anna Diamond
cartridges to be perfectly matched with an extremely wide array
of different tonearms. Because of the nature of SLM-based
construction, each cartridge body is cosmetically unique and
will show small dimples or lines under close examination.
Arguably one of the most signifi cant advancements in the MC
Anna and the MC Anna Diamond is our dramatically higher effi ciency magnet system.
The optimized geometry of the
magnet system combined with choice materials like neodymium
and iron-cobalt offers an unprecedented consistency of the
fl ux density within the systemís air gap. Due to an increase
of active material inside of the magnet system, the magnetic
fi eld strength is delivered more uniformly, allowing each coil to
sense identical fl ux density regardless of its position. Because
of this, dynamics and impulse linearity are preserved to an
overwhelming extent.
The use of this new optimized magnet system allows for the
use of a lightweight, non-magnetic armature, which also
provides noteworthy benefi t to the dynamic capability of the
MC Anna and the MC Anna Diamond cartridges. The reason
for this is that our specially designed precision moulded nonmagnetic
armature does not alter the magnetic fi eld during
movement. Hence when combined with ultrapure oxygen-free
copper coil wire, it delivers perfect reproduction of the cantilever
movements without compromise. The material applied for the
armature has very high strength and rigidity.
Because the new magnet system delivers a tremendous magnetic
fl ux density, the need for design compromises is effectively
eliminated. It is due to this aspect that the amount of coil windings
required to achieve signifi cant output voltages is reduced to a
minimum, resulting in a further reduction in moving mass.
The new magnet system has also allowed for more
spaciousness within the air gap, allowing for coil windings to
be done completely independent of each other, without any
overlap or interaction between them and with an extreme
precision in each coil turn in all layers. The cumulative result of
these improvements simply delivers more lifelike reproduction,
with nearly boundless imaging, dimensionality and dynamics.
Increase in dynamics, resolution and
richness in details

The MC Anna and the MC Anna Diamond also employ a
greater degree of control over vibrations by a way of a newlyimproved
Wide-Range armature Damping system (WRD).
By extending the armature beyond the coils, it can interface
directly with the rubber dampers, which sandwich a small
heavy disc of platinum. This offers more consistent movement,
and thereby better stereo perspective and transient delineation.
System resonances are also damped by the use of the Thermo
Plastic Elastomer (TPE) compound which comprises the
bottom cover assembly.
As in the entire Exclusives series cartridges, the MC Anna and
MC Anna Diamond make use of Ortofonís Replicant 100
diamond, known for its thin and light profi le 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 in
the MC Anna model offer extreme transparency, speed and
responsiveness. The addition of a solid Diamond cantilever
found in the MC Anna Diamond provides the best possible
interface between the stylus and armature, owing to its
hardness and crystal structure. The improvements found in the
use of a Diamond cantilever have redefi ned the boundaries of
analog reproduction, presenting greater inner detail, subtlety,
and depth like never before.
Flexibility and performance with
a range of compatibility
Output impedance of 6 ohm and a low-to-medium output
voltage of 0.2 mV make the MC Anna cartridges perfect
partners for most MC phono preamps and step-up
transformers, including the Ortofon ST-80 SE MC transformer.
Both models are a perfect match for a high-mass, highprecision tonearm with gimbaled bearing.
Both the MC Anna and the MC Anna Diamond focus on
providing music in its entirety without compromise, offering
an ideal balance of precision and musicality to provide an
engaging experience on a whole new level. With fi ne attention
to both micro and macro dynamics combined with fl uid tonality
and texture, the MC Anna and MC Anna Diamond will shatter
the boundaries of recorded music forever.
Considering Ortofonís world-class knowledge in analogue
sound reproduction, the MC Anna and the new MC Anna
Diamond will undoubtedly provide sound which is literally
unsurpassed and simply has to be experienced.
