Ortofon SPU GTX S Cartridge

Ortofon SPU GTX S

The Ortofon SPU GTX S combines the traditional sound quality of the SPU series with the latest technology and offers a high-precision moving coil cartridge with integrated step-up transformer.

Technical Highlights

• Spherical needle: The rounded tip of the spherical needle contacts the groove walls of the record and ensures a uniform and balanced sound reproduction.
• Integrated step-up transformer: The transformer, developed in collaboration with Lundahl Transformers , offers high output power and reduces noise. The cartridge can be connected directly to any phono preamplifier or amplifier - no additional equipment is required.
• Housing material: The housing is made of a glass fiber reinforced co-polymer, which is used for the first time in the SPU series. This material ensures stability, low resonance and optimal shielding of the generator system.
• Precise manufacturing: The handmade construction in Denmark ensures the highest quality workmanship and durability.

technology and variants

• The SPU GTX S is a moving coil pickup with integrated step-up transformer, glass fiber reinforced housing and spherical diamond.
• The SPU GTX E has the same basic construction, but is equipped with an elliptical diamond for even more precise sound reproduction.

Additional features

• Tracking angle: 20° for precise tracking.
• Weight: 38 g, optimized for compatibility with high-quality tonearms.
