For the new MC Diamond cartridge, the Ortofon Wide Range Damping System (WRD) has been re-engineered to include an enhanced rubber suspension, specially developed in-house.
The WRD system was originally introduced in the MC 20 Mk II in 1979 and was also subsequently used in the MC A90, MC Windfeld, Xpression, MC Anna, MC Anna Diamond and MC Century phono cartridges. 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 new rubber compound formula is based on the Multi Wall Carbon Nano Tube (MWCNT) highly efficient nano filler. The new MWCNT-based compound offers desirable mechanical properties, which allow for optimal interaction between compliance and damping, that improves stability and playback and ensures unparalleled sound quality.
