Ortofon SPU GTX S

SPU GTX S The SPU GTX S delivers the best of both worlds, blending the musicality and rich tonal character that have defined Ortofon’s SPU series for decades with the latest innovations in audio technology. Rediscover the rich, vintage warmth of vinyl with the Ortofon SPU GTX S, featuring a spherical stylus. The spherical stylus is the most common stylus shape and has a rounded tip that contacts the groove walls of the record, offering a balanced, smooth sound. The built-in MC step-up transformer provides high-output, low-noise performance, preserving the classic SPU audio fidelity. Precision engineering and craftsmanship SPU GTX cartridges are hand-built by experienced workers in Denmark. Their unibody housings are molded in one piece from a specially selected glass-fiber reinforced co-polymer, never before used for SPU cartridges. This ensures a form-factor stable, rigid, and low resonance housing for the fine generating system. The bottom cover is molded from the same new material, encapsulating the engine in a uniform material and design. SPU GTX S is a moving coil cartridge with a built-in step-up transformer, a glass-fiber reinforced housing, and a spherical diamond. SPU GTX E shares the same general setup and construction as GTX S, but the configuration is upgraded with an elliptical diamond. Built-in step-up transformer The SPU GTX Series is designed to simplify your setup without compromising sound quality. When developing the GTX series, Ortofon chose to develop the new step-up transformers in collaboration with the company Lundahl Transformers. Thanks to the built-in step-up transformer, these cartridges connect directly to any phono stage or amplifier with the ease of a moving magnet cartridge – no extra equipment needed.
