SPU 90th Anniversary

Description

The Ortofon SPU 90th Anniversary provides reproduction of sound that is unsurpassed in its neutrality, detail and dynamic range. Much like Robert Gudmandsen’s revolutionary that which originally brought the SPU cartridges to the market in the 1960s, endless research and conceptual design has been placed into this special anniversary model.

For the first time in history the SPU has been graced with a completely new patent-pending magnetic system, which retains all of the characteristics that put its brethren in a class of their own.
Features

In this cartridge, a one piece body makes the direct connection between the generator system and the wooden housing ensuring both a perfect rigid connection and extremely high internal damping.

A nude elliptical diamond stylus graces the aluminum cantilever, representative of the legacy created by SPUs past, along with a black painted, grinded wood body.

Also adding to the sonic performance of the SPU 90th Anniversary is nothing but the best internal coil wiring, comprised of silver plated ultra high purity (6NX) copper wire, to ensure that each and every movement of the stylus is captured faithfully without loss. The internal terminal wiring is made of ultra high purity (6NX) silver wire, with gold plated terminal connectors.
