Ortofon SPU Classic N Phono Cartridge
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 Classic NThe SPU Classic N provides the same sound reproduction properties as the SPU Classic GM series, but is sold without the integrated headshell unit. The SPU Classic N is a Moving Coil (MC) cartridge with an 18µm spherical stylus profile. Listeners who wish to mount the SPU Classic on a traditional headshell may do so, and those with vintage SPU-type headshells can use the Classic N to recreate an authentic and functional SPU cartridge.
