Ortofon MC Diamond

The Ortofon's greatest phono cartridge ever, the MC Diamond delivers recorded music like you’ve never heard it before

Ortofon aspires to provide the ultimate musical experience through a mixture of innovation, technical expertise and inspiration. This new state of the art phono cartridge, representative of numerous Ortofon design elements and ideals, is truly exemplary of the highest degree of performance possible in contemporary analogue playback technology.

Featuring a titanium body, optimized magnet system, diamond cantilever and a new rubber suspension, the MC Diamond provides an entirely new level of experience for audiophiles.

“This is recorded music like you’ve never heard it before – the most authentic vinyl experience in the world”, - said by Leif Johannsen, Ortofon’s Chief Officer of Acoustics and Research.

Newly enhanced rubber suspension

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.

Cartridge Body

The cartridge body of the MC Diamond is made of titanium using our custom Selective Laser Melting (SLM) technique. This technique allows for precise control of the density of the body, which provides extremely high internal damping, and results in a significant reduction in vibrations and enhanced sound quality.

Magnet System

The MC Diamond’s magnet system combines choice materials, optimized geometry, and unrivaled consistency that deliver unmatched performance. Together with the non-magnetic armature, the result is vivid, highly-accurate audio reproductions defined by nearly boundless dimensionality.
