Ortofon SPU #1S

Ortofon SPU #1S

SPUs

No other company has ever retained a phono cartridge model in their product range for so many years. The SPU was used by early broadcasting companies among whom the Ortofon brand name was already well known from the first moving coil system - the Ortofon mono system in the small black A-housing. The so-called “Ortofon sound“ became synonymous with the sound from the SPU, at an early stage.

The SPU #1 S is a Moving Coil cartridge with an 18 µm spherical stylus profile.

The SPU 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.

For moderate and high mass tonearms with SME connections.
