Ortofon SPU Synergy GM Moving Coil Cartridge

Ortofon SPU Synergy GM

A modernisation of the classic SPU design featuring optimisations 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 0.5 mV, relaxing the requirement for high gain transformer or active pre amplification 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.
