Ortofon MC Windfeld MC Pickup

Ortofon MC WindfeldPer Windfeld

The MC Windfeld was developed in 2008 using state-of-the-art technology.

This highly advanced design, which is the world’s most hi-tech analogue cartridge, may be seen as a tribute to Ortofon’s departed engineer Per Windfeld, who had for more than 30 years been a feature of the high-end culture as the head of development behind amazing cartridges such as the Ortofon MC 20 Super, Concorde, MC Rohmann, MC Jubilee, Kontrapunkt Series, etc.

MC Windfeld is designed by a team headed by Mr.Windfeld’s successor, Leif Johannsen, the Ortofon’s Chief Officer of Acoustics and Technology and the cartridge bears Mr.Windfeld’s name – his initials “PW” are inscribed in gold on the cartridge’s side.

The Windfeld retains many of Per Windfeld’s earlier design innovations, including Wide Range Damping (WRD) system, the ultra-fine polished version of extremely low mass, large-vertical-contact Replicant 100 diamond, capable to extract musical information from the grooves with a greater degree of accuracy than any other kind of needle and a strong neodymium magnet system with a Field Stabilizing Element (FSE) located within the magnet system.
The MC Windfeld can ideally be combined with the Ortofon TA-110 and TA-210 tonearms and the ST-80 SE MC transformer.

Design and manufacturingPer Windfeld

Historically, Ortofon has always followed its own path with regard to the mechanical design of the cartridge housing, because mechanical rigidity and total freedom from resonance in the audible range is a precondition for optimal sound quality
In the MC Windfeld, Ortofon continues to build on the structure of the Kontrapunkt Series, in which the cartridge housing’s contact with the pick-up arm takes place through three hard, well-defined points, i.e. a kind of spikes. This means that the mechanical integration of the cartridge and the pick-up arm are always absolutely perfect.

We have reinforced the construction by allowing one central structure, made in a special alloy, to reach from the 2.5 mm threaded holes at the top all the way down around the motor system at the bottom. This makes the MC Windfeld one of Ortofon’s strongest and resonance-free cartridges, with a direct mechanical connection between the motor and the tonearm. What this means for the dynamics, resolution and richness of detail in the sound simply has to be experienced.

But the Ortofon MC Windfeld is also unique in cosmetic terms: the parts of the cartridge housing are produced with matt and polished black surfaces. The underside facing the record is covered by a new shield, which reinforces the mechanical structure. Per Windfeld’s characteristic initials in gold, which decorate the sides of the cartridge housing, stand as a signal to the outside world that this technologically advanced cartridge is Ortofon’s finest, most accurate and in our own opinion also best-sounding design.

We recommend a thorough listening test using the best equipment, and invite serious audiophiles to pay tribute to Per Windfeld with this serious candidate for the world’s best cartridge.

Combining some of Mr. Windfeld’s innovations pw

Neodymium magnet with FSE

The magnet system combines Per Windfeld’s designs for the much-admired Kontrapunkt series and the MC Jubilee. It is based on an extremely strong, compact neodymium magnet, which makes the generator system both compact and through its minimal dimensions also lighter.
A so-called Field Stabilising Element, 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 minimising 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 between the high-end system’s loudspeakers!

WRD system
One of the important components is the WRD system (Wide Range Damping), in which a small, heavy disc of exotic metal is clamped between two rubber absorbers with different properties. This makes sure that the tracking performance is maintained simultaneously with the perfect damping in the whole frequency range, with the effect that distortion and resonance are avoided.
The WRD system, which was originally introduced in the MC 20 Mk II in 1979 and was also used in the MC Jubilee and many of Ortofon’s other top-class cartridges, is one contributory reason why the MC Windfeld, while achieving the most linear frequency response and the highest upper frequency limit ever, at the same time tracks a fantastic 100 µm at a vertical tracking force of 2.6 grams.

Diamond and a coil technologypw

The finest diamond in the world

PW diamondAnother precondition 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 needle. To achieve this, the Ortofon MC Windfeld uses an ultra-fine polished version of the unique Ortofon Replicant Stylus 100.
This diamond, which is already known from products such as the MC 3000 Mk II and MC 5000, is incredibly small and light, but has an extraordinarily large vertical contact surface despite its minimal radius of rounding. Correctly fitted at a vertical angle of 23 degrees, an Ortofon Replicant Stylus 100 will read the musical information in the grooves of a record with a greater degree of accuracy than any other kind of needle.

New coil technology and expensive materials

Zero-loss transmission of the diamond’s movements to the expensive Aucurum coils of gold-plated, 99.999999% oxygen-free, monocrystalline copper is achieved in the Ortofon MC Windfeld via a cantilever in boron (just as in the MC Jubilee), which combines a low moving mass with a very high degree of mechanical rigidity.
A special design of armature makes it possible to position the coil turns extremely precisely in several layers. This technology achieves higher channel separation, lower distortion and better channel balance. A low output impedance of 4 ohm and a medium output voltage of 0.3 mV makes the Ortofon MC Windfeld a perfect partner for most step-up transformers, e.g. Ortofon ST-80 SE, as well as active MC pre-amps.

The MC Windfeld can ideally be combined with the Ortofon TA-110 and TA-210 tonearms.
