Features:
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.
