Ortofon SPU Synergy GM Cartridge

The SPU Synergy GM modernizes the classic SPU design with a number of optimizations designed for optimum compatibility and sonic purity.

The SPU Synergy features a wood-based housing and has a revised generator system which allows for a maximum output of 0.5 mV, relaxing the requirement for high gain transformer or active preamplification systems.

While still making use of a highly polished Nude Elliptical stylus, the stylus tip mass has been reduced significantly, resulting in reduced VTF and higher tracking ability.

A little background of the SPU cartridge.

The term “SPU” stands for “stereo pick-up” as phono cartridges were called “pick-ups” in the 1950s and 1960s. The original SPU was introduced in response to the demand for cartridges to reproduce the new stereo records. Based on Ortofon’s already 10 year old technology and experience in mono cartridges, the SPU immediately set the standard for professional and audiophile applications.

Back in 1958 the Ortofon SPU sounded like no other cartridge because it was way ahead of its competition. Today the SPU still has a sound that is definitely its own and it enjoys a remarkable following – in particular among audiophiles whose systems are comprised of vintage valve equipment and horn or reflex speakers.

But with no other cartridge over the course of half a century, have we ever had to take so much care in respecting this original sound when improving technical data, as with the SPU model. As a result  and in order to show considerations for this goal, you will after 60 years still find the basic visuals, the original design, as well as the original elements in the construction of the magnetic circuit kept fully intact.

Evidently the product has changed throughout its evolution. New possibilities in regards to housing materials, diamonds and magnetic system have been employed to improve the SPU and its performance whilst at the same time we remain faithful to the original concept. It is also clear that in a period of 60 years certain components will be changed as the suppliers no longer make them and replacements must be found.
