Ortofon SPU Synergy GM
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 0.5 mV, 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.
