BRAND: ORTOFON
SERIES: SPU Wood A
TYPE: Cartridge
Thank you for choosing an Ortofon SPU cartridge for your turntable. All Ortofon SPU-cartridge models are highly indebted to their SPU-ancestor launched in 1958, when the original Ortofon stereocartridge was born.
OVERVIEW
So, ever since the various Ortofon SPU models announced in this manual, have never compromised with the basic design – responsible for the so-called “Ortofon Sound”, world wide related to these cartridges. Refinements on the models have taken benefit from the use of new materials and improved stylus types, to gain the outstanding reproduction qualities.
