The io uses the same power amplifier and phono stage as its larger brother, the multi-award winning Brio. The io aims to deliver exceptional sound quality in a smaller and more cost effective package. The class A/B circuit shares its DNA with the rest of Rega’s amplifiers, and as usual, great care has been taken in component selection. Sanken output transistors and an Alps volume potentiometer and a linear power supply that enables an output of 30 watts per channel into 8 ohms.
Two line level inputs and a high quality moving magnet phono input are available as sources. There is a headphone output provided on the front of the unit for powering standard hi-fi headphones; this is driven from the power amplifier stage of the unit through relays to avoid signal degradation when headphones are inserted or the product is muted. A new remote handset is included as well.
The all new io amplifier is designed with every music lover in mind. Simple to setup and operate, the io is designed to integrate seamlessly into any hi-fi system. The compact size allows it to be used in a variety of systems and delivers a performance well beyond its price point. As you would expect, there is a high quality built in MM (moving magnet) phono stage, two line level inputs, a redesigned mini remote control handset and high quality headphone output that is cleverly integrated to deliver optimum performance without compromising the audio circuit. All of these features combine to deliver a powerful, well balanced musical performance at an incredible price.
