About the SPU GTX S
The Ortofon SPU GTX S is a premium moving coil (MC) phono cartridge from the iconic SPU series, featuring a built-in MC step-up transformer developed with Lundahl Transformers for direct connection to MM phono inputs without additional equipment. It combines the rich, vintage tonal character of classic SPUs with contemporary innovations like a one-piece glass-fiber-reinforced copolymer housing for low resonance and stability. Equipped with a spherical diamond stylus (R 18 μm), aluminum cantilever, Alnico magnets, high-purity OFC copper quad coils, and Ortofon's exclusive suspension system, it delivers balanced, smooth sound with excellent tracking. Handcrafted in Denmark, it weighs 38 g and outputs 4 mV for easy integration and low-noise performance.
