Audio Note IO LTD MC Cartridge + PSU

The Io Ltd is the most extreme cartridge Audio Note make and is the finest cartridge we know of. It disposes of the Alnico magnets found in the other models and replaces them with field coils - basically windings of wire that when a current is passed through them they generate the magnetic field. This cartridge requires an external power supply to power these field coils and also an additional two wires to the cartridge to power it - these can either be rewired into most tonearms or run along the outside of the arm tube. It’s output is lower again than the other Io’s at 0.04mV. Quite simply this is the best cartridge I’ve ever heard, it has a raw musicality that is quite unique and is totally absorbing to listen to, yet like the other Io cartridges, pinning down its sound is very difficult - it just disappears!
