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, the MC Windfeld and many of Ortofon’s other top-tier cartridges, is one significant reason why the Xpression, while achieving the most linear frequency response and a high upper frequency limit, at the same time tracks a fantastic 90 μm at a vertical tracking force of 2.6 grams.
