SPU Classic N
The SPU Classic N is a Moving Coil (MC) cartridge with an 18µm spherical stylus profile sold without an integrated headshell unit. Those with vintage SPU-type headshells can use the Classic N to recreate an authentic and functional SPU cartridge.
Listeners who wish to mount the SPU Classic on a traditional headshell may do so by using the SPU N adaptor.
NB: Vintage SPU-type headshells are no longer available.
