The SPU Classic N provides the same sound reproduction properties as the SPU Classic GM series
The SPU Classic N is sold without the integrated headshell unit.
The SPU Classic N is a Moving Coil (MC) cartridge with an 18 m 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. NB: Vintage SPU-type headshells are no longer available.
