Ortofon SPU Meister Silver GM MKII MC-Cartridge

The Sound Of Excellence

In the late 1950s the iconic SPU cartridge range featured Ortofon’s newly introduced low coil resistance and impedance concept. As a basis for reproducing superb high frequencies, this concept has been continually improved and refi ned in the decades since.

With the recent launch of both the SPU Anniversary 85 and MC Rondo cartridges, Ortofon has introduced a new era of wood-based housing structures. The benefi ts of this natural material for cartridge housings mimic the centuries old tradition of hand crafted musical instruments with all the acoustic benefits.

The new developed Ortofon Synergy SPU-cartridge continues the predecessor’s concept whilst adding a new large sound image. The addition of unsurpassed technical data adds up to a highly sophisticated package. The exceptional black polished Urushi painting on the new SPU-housing suggests a precious jewel-like appearance. The musical instrument theme continues - the superb black glazing paint is of a quality found only on famous name pianos. Not only is the visual impression most attractive but the new transducer system allows extraordinary Synergy of sonorous sound.

Very low coil-resistance combined with unusually high output (achieved by using Neodymium magnets in a soft iron circuit with high saturation) was decisive for reaching the high signal to noise ratio acheived with the new Synergy SPU-cartridge.

By controlling the cantilever and armature movements in air-gap with very high-magnetic induction, Ortofon has used its comprehensive expertise in designing the right type of damping for the new system.

The nude, finely polished elliptical diamond in combination with the aluminium cantilever has both had essential infl uence on the fi nal frequency-response.
