The SPU Royal NM provides the same sound reproduction properties as the SPU Royal GM series, but is sold without the integrated head shell unit.
The SPU Royal NM 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.
Listeners who wish to mount the SPU Royal NM on a traditional headshell may do so, and those with vintage SPU-type headshells can use the Royal NM to recreate an authentic and functional SPU cartridge.
