The Maia 3 is an 85 watt per channel high performance audio power amplifier housed in the Rega custom built extruded aluminium case. The amplifier has a fully protected output stage with DC and electronic thermal protection, and a power monitor for both transformers. High quality Evox capacitors have been used in the signal path throughout.

The Maia 3 uses the Rega "common base driver stage" circuit design. Rega used circuit modelling and listening tests to design this amplifier resulting in superb reliability and exceptional sound quality. Sanken 200w output transistors are used in a high current output stage and will drive the most awkward of speaker systems.
