The SPU Classic N can be defined as the version of the SPU Classic GM mkII without the characteristic integrated SPU cartridge holder, which allows it to be used with all types of reading arms. Let us remember that the SPU was introduced to the market in 1958 in response to the demand for capsules to play the new stereophonic vinyl records. The acronym SPU is the acronym for "Stereo Pick-Up" or "pick-up capsule", since until then (that is, during the 50s and 60s of the last century) the capsules on the market were called "capsules" dry.
Also fundamental to the SPU is the relevance that Robert Gudmandsen, one of Ortofon 's most brilliant engineers, had in its development. Based on 10-year-old technology and Ortofon 's experience in monophonic cartridge design, the SPU immediately set the quality standard for pickup cartridges for professional and audiophile applications, while also setting the path forward. in designing products in its class for the next 57 years.
Supplied as standard with an SPU in N adapter, the SPU Classic N is a moving coil cartridge that mounts an 18 um radius Nude spherical diamond stylus, which in conjunction with Ortofon 's exclusive SPU signal generation concept allows you to reproduce all types of vinyl recordings with a fresh, vital and spacious sound (thanks to excellent separation between channels).
