Product Description

The range of Io cartridges from Audio Note UK are renowned throughout the world for their incredible quality and their effortless ability to reproduce music to the highest possible standards. The unique nature of the Io design runs contrary to most accepted criteria, but the end result is a relatively small selection of hand-built moving coil cartridges, which are second to none with regard to dynamic range, tonal balance, channel separation, timbral reproduction, and a lack of colouration and surface noise. The cartridges are not able to be mass produced due to their design, and as a result are extremely time-consuming to produce. In use, they require a tone arm of very substantial rigidity, and must be combined with a properly matched, high-ratio 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 the Io 1 features ALNICO magnets, silver-wound generator coils and a titanium cantilever with an Audio Note AN Type-2 profile, diamond stylus. The Io-I, has generator coils wound on a Swedish-made former and is available with either red or blue aluminium sides.

Please note that due to the construction process, Io cartridges may not always be available from stock. Read the product review.
