Ortofon SPU Royal GM MKII
The SPU Royal GM and N models were released in 1998, together with the Jubilee cartridge to celebrate the Ortofon 80 year anniversary.
The SPU Royal GM MKII provides a playback experience that embodies the essence of analog, with generous refinements which bring the legendary SPU cartridges into the realm of unrivaled perfection.
The addition of Ortofon’s unique Replicant 100 stylus and reduced tip mass ensures open and detailed sound reproduction for a purely exquisite listening experience.
Electrum coils, consisting of a gold and silver alloy, provides uncolored and precise transmission of armature movements while the slightly modified damping system makes it possible to reduce VTF and achieves a higher level of linearity.
High purity 6-nines copper wiring ensures impeccable signal transmission and preservation of the finest of microdynamic detail.

Ortofon’s SPU cartridges continue the tradition of the first ever Moving Coil cartridges as originally engineered by Mr. Robert Gudmandsen and produced by Ortofon in the late 1950s. Praised for their refined linearity and full body, these cartridges have remained a favourite throughout the years, both for modern and vintage high-end applications. This year we decided to give our SPU fans around the world an opportunity to get a collection of the four most famous SPUs, each of them being a very special collector's item.
