Ortofon MC Windfeld Low Output Moving Coil Cartridge
This highly advanced design, which is the world’s most hi-tech analogue cartridge, may be seen as a tribute to Ortofon’s departing engineer Per Windfeld, who has 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, Concorde, Rohmann, Jubilee, Kontrapunkt, etc. Historically, the hi-fi culture has offered several exciting products that will long stay in the memory. For example, it is hardly an exaggeration to refer to Ortofon’s legendary SPU moving coil cartridges as state of-the-art products and milestones in hi-fi -culture. The last 30 years have seen an incredible number of successes. This is why Ortofon is now paying tribute to Per Windfeld with a newly developed, state-of-the-art, moving coil cartridge in the absolute high-end class.
Precision knowledge rather than voodoo and wishful thinking
Ortofon is a company that is built on ingenious innovations, proud traditions and incredible volumes of accumulated, precision knowledge of transducer technology. The foundations were built by the company Fonofi lm Industri A/S, founded in 1918, which won international success and acclaim by synchronizing sound and pictures in the fi lm industry. Nowadays Ortofon produces not only the best cartridges in the world, but also microscopic precision parts for industrial measuring instruments and tools that no one else in the world is able to compete with. You only gain the position as market leader when you base your business on know-how and precision knowledge rather than the voodoo and wishful thinking that characterises the high-end brands of others in the industry. The Ortofon MC Windfeld combines the best of the innovations that Per Windfeld and his team developed in the years following the launch of the original MC 20 in 1977: One of the important components is the patented 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.
The finest diamond in the world
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-fi ne 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 fi tted 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 as well as active MC preamps.
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. A so-called Field Stabilising Element guarantees that the force field remains stable regardless of the movement of the armature. 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!
