Type: SPU CLASSIC N

  • Ortofon cartridge

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 18µm spherical stylus profile.
Listeners who wish to mount the SPU Classic on a traditional headshell may do so by using the 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.
