The SPU Royal GM was released in 1998 to celebrate Ortofon's 80th anniversary of manufacturing precision phono cartridges. The SPU Royal GM MkII is a slight update on the original Royal, and provides a playback experience that embodies the essence of analogue reproduction, with generous refinements which bring the legendary SPU cartridges into the realm of unrivaled perfection.
The model uses Ortofon’s unique Replicant 100 stylus and the reduced tip mass ensures open and detailed sound reproduction for a purely exquisite listening experience. Electrum coils, consisting of a gold and silver alloy, provide uncoloured and precise transmission of armature movements, while the slightly modified damping system makes it possible to reduce the vertical tracking force compared to the original version, thus achieving a higher level of linearity.
The Ortofon Royal has a justified reputation among hi-fi owners and reviewers as among the best of analogue reproduction. Capable of remarkable delicacy, combined with superb dynamics, this is rightfully named 'Royal'.
