Ortofon SPU Royal GM MkII
The SPU Royal GM model was released in 1998 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.
