The Ortofon MC Windfeld phono cartridge

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 ;

Ortofon MC 20 Super, Concorde, MC Rohmann, MC Jubilee, Kontrapunkt Series

Diamond and coil technology

Ortofon Replicant 100 - the finest diamond in the world

The MC Windfeld features an ultra-fine and extra polished version of the unique Ortofon Replicant 100 stylus. Replicant 100 is also used in the MC A90, Xpression, MC Anna and MC Cadenza Bronze cartridges, providing more responsive and transparent sound reproduction.

Another 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.

Neodymium magnet with Field Stabilising Element

Combining some of Mr. Windfeld's innovations

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 Field Stabilising Element (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 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!

The Wide Range Damping (WRD) system

One of the important components is the WRD system, 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.
