Product Description

The Io range of cartridges from Audio Note UK are world-renowned for their stunning quality and their effortless ability to reproduce music to the highest standards. The revolutionary nature of the Io design runs contrary to most accepted design criteria, but the result is a small range of hand-made moving coil cartridges that are second to none in terms of dynamic range, tonal balance, separation, timbral reproduction, and lack of colouration and surface noise. The cartridge designs do not lend themselves to mass production and as a result are extremely time-consuming to produce. They require a tone arm of very substantial torsional rigidity, and must be combined with a matching step-up transformer in order to achieve the best possible linearity and dynamic signal transfer.

All Io cartridges are hand-built in the UK to exacting standards and feature ALNICO high-density magnets, silver-wound generator coils and a titanium cantilever with an Audio Note AN Type-1 profile, diamond stylus. The Audio Note Io Gold has generator coils wound on a Permadure-iron former and is supplied with gold-plated gun-metal sides. The highest possible tolerances are used when selecting the cantilever, stylus and generator.

Please note that due to the hand-made nature of Io cartridges, they are often not available from stock.
