Ortofon SPU Royal N
A Briefing on Ortofon's SPU CartridgesOrtofon’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 favorite throughout the years, both for modern and vintage high-end applications. The latest incarnation of SPU cartridges feature a wood-based integrated headshell to further reduce resonance and provide an authentic and attractive aesthetic.
Details on the Ortofon SPU Royal NThe SPU Royal N provides the same sound reproduction properties as the SPU Royal GM series, but is sold without the integrated headshell unit. The SPU Royal N 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 N on a traditional headshell may do so, and those with vintage SPU-type headshells can use the Royal N to recreate an authentic and functional SPU cartridge.
