SPU Classic



The SPU Classic was reintroduced in 1987. The model of 1987 was incrementally improved since its inception in 1959, as new materials, manufacturing techniques and processing technologies were developed, though 18μm Nude spherical stylus and Aluminium-Magnesium alloy housing remained untouched.

The model is known for its dynamic and powerful sound reproduction where the special SPU character is most pronounced and original.

Equipped with Nude spherical stylus the cartridge has sound that is both rich and silky. With its linearity and full body, SPU Classic has remained a favorite throughout the years, both for modern and vintage high-end applications.

This cartridge is a perfect solution for the playback of both early and modern and contemporary stereo recordings.
