A Briefing on Ortofon's SPU Cartridges
Ortofon’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 GM MKII
The SPU Classic GM MKII, known for its dynamic and powerful sound reproduction, is a Moving Coil (MC) cartridge with an 18µm spherical stylus profile. The SPU Classic series embodies the essence of the original Moving Coils and are a perfect solution for the playback of both early and modern and contemporary stereo recordings.
