OverviewFeaturesReviewsSpecifications

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.
