ORTOFON SPU CLASSIC N

The 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 by using SPU N adaptor. Those with vintage SPU-type headshells* can use the Classic N to recreate an authentic and functional SPU cartridge.
