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 Synergy G
The SPU Synergy GM modernizes the classic SPU design with a number of optimizations designed for optimum compatibility and sonic purity. The SPU Synergy features a wood-based housing and has a revised generator system which allows for a maximum output of 500µV, relaxing the requirement for high gain transformer or active preamplification systems. While still making use of a highly polished Nude Elliptical stylus, the stylus tip mass has been reduced significantly, resulting in reduced VTF and higher tracking ability.
