The story behind the MC Anna cartridges
Historically Ortofon has a long tradition of paying tribute to persons who have been highly influential within the high-end audio culture and in music culture and history in general. In honor of these remarkable persons, Ortofon has introduced numerous products throughout the years, including the SPU Meister, MC Rohmann, Kontrapunkt series and Windfeld cartridges. Continuing this tradition with the MC Anna and the MC Anna Diamond, Ortofon dedicates these flagship cartridges to the operatic soprano Anna Netrebko, a virtuoso whose performance displays a formidable technical arsenal of endless versatility. With the dedication of the MC Anna, Ortofon once again emphasizes the company’s unchanging commitment and devotion to the music and to the purest delivery of recorded sound. Much like Anna Netrebko, Ortofon aspires to provide the ultimate musical experience through a mixture of innovation and technical expertise, combined with inspiration that goes beyond mere thought to reveal true inner emotion.
 
Higher efficiency magnet system
The optimized geometry of the magnet system combined with choice materials like neodymium and iron-cobalt offers an unprecedented consistency of the flux density within the system’s air gap. Due to an increase of active material inside of the magnet system, the magnetic field strength is delivered more uniformly, allowing each coil to sense identical flux density regardless of its position. Because of this, dynamics and impulse linearity are preserved to an overwhelming extent. The use of this optimized magnet system allows for the use of a lightweight, non-magnetic armature, which also provides noteworthy benefit to the dynamic capability of the MC Anna Diamond. The reason for this is that our specially designed precision moulded non-magnetic armature does not alter the magnetic field during movement. Hence when combined with ultrapure oxygen-free copper coil wire, it delivers perfect reproduction of the cantilever movements without compromise. The material applied for the armature has very high strength and rigidity.
