THORENS SPU TD 124

The SPU 124 modernizes the classic SPU design with several optimizations designed for optimum compatibility to the new Thorens TD 124 DD.

The SPU 124 features 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.
