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. 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. Mounting All SPU-cartridges are designed to bring optimum performance, when the tonearm mounted with the cartridge is adjusted parallel to the record surface, at recommended tracking force.
When antiskating adjustment is possible, we recommend a 50% higher value, when using SPU-cartridges with the Ortofon Replicant stylus, compared to normal setting at recommended tracking force.
SPU Classic Series The SPU Classic series, as the name implies, embodies the essence of the original Moving Coils. With their linearity and full bodies, these cartridges are a perfect solution for the playback of both early and contemporary Stereo recordings. The SPU Classic series is known for its dynamic and powerful sound reproduction, without any roughness, minimum of intermodulation distortion and a splendid channel separation, the images being fi rm and positive. The SPU Classic N and SPU Classic NE cartridges, with their half-inch adaptor, provide the ability to mount the unit on standard headshells, as well as in a wider range of tonearms.
