The gateway to the most admired and iconic of the Ortofon pick-up families, the SPU was introduced to the market in 1958 in response to the demand for capsules to play the new stereo vinyl records. The acronym SPU stands for "Stereo Pick-Up" or "Pick-Up Capsule", because until then (i.e. during the 1950s and 1960s) the capsules on the market were simply called "capsules". Also fundamental to the SPU is the role played in its development by Robert Gudmandsen, one of the most brilliant engineers at Ortofon.
Based on 10-year-old technology and Ortofon 's experience in monophonic cartridge design, the SPU immediately defined the quality standard for pick-up cartridges for professional and audiophile applications, and set the standard for product design in its class for the next 57 years. With these premises in mind, the SPU Classic GM mkII, featuring a Nude spherical profile diamond stylus, embodies the essence of the original Ortofon moving coil designs, offering a perfect solution for reading vintage and contemporary stereo recordings with a dynamic and powerful sound that is virtually free of intermodulation distortion and with splendid channel separation.
