Product description
The SPU was launched back in 1958 in response to the demand for cartridges to reproduce newly-introduced stereo records. The SPU immediately set the standard for professional and audiophile applications and paved the way for the next 60 years of high-end cartridge design.
The SPU is the only Ortofon stereo cartridge that has survived since 1958 in its original form and from all over the world has gained a reputation second to none for its outstanding analogue sound reproduction.
With the SPU Century, the bar is raised for both its modern and vintage counterparts. The new Ortofon SPU Century has gone to the next level by reducing unwanted vibrations within the cartridge. Our extensive knowledge of vibration and characteristics of different materials, competences in magnetism, mechanical design and new technologies has been applied for optimization of this model.
