Ortofon's OM series represents over five decades of precision engineering in Moving Magnet cartridge technology, earning acclaim from audiophiles and music enthusiasts worldwide. These cartridges showcase Ortofon's innovative approach to tonearm compatibility through a clever removable weight-plate system built into the mounting bracket. For standard tonearms, simply retain the weight-plate, whilst low mass tonearms benefit from removing it entirely, reducing the cartridge mass to just 2.5g for optimal tracking performance.
The OM 5E incorporates an Elliptical stylus design that ensures balanced, distortion-free reproduction of your vinyl collection. The contoured shape of elliptical diamonds allows superior tracking of groove oscillations compared to spherical alternatives, resulting in enhanced accuracy and reduced distortion during playback.
A standout feature of the OM 5 Series lies in its comprehensive range of interchangeable replacement styli, allowing you to optimise your system's performance without replacing the entire cartridge. This modular approach means you can upgrade your sound quality by simply swapping the stylus, with options including the 3E, 5E, 10, 20, 30, 40 & 78, plus the D 25 M variant to suit various applications and budgets.
