The Osiris is the culmination of 32 years’ experience in solid-state amplifier development. A no compromise, super high performance, 162 Watts into 8 Ohms (250 Watt 4 Ohms), dual mono amplifier housed in a custom Rega CNC machined aluminium case. Designed around "minimalist" high gain power amplifier and "passive pre-amplifier" circuit topology, a passive volume control and a single stage of power amplification between the input and the speakers, the Osiris offers unrivalled performance and build quality.
All these features combine to create the supreme level of performance found in the Osiris and provide a perfect partner for our Isis CD player. We hope that you enjoy this product as much as we have enjoyed creating it.
The Osiris uses two low noise, purpose designed 400VA toroidal transformers using high-grade, fully bonded core material. The transformers are mounted to the chassis using Rega's innovative mounting technique which eliminates noise being transferred from the transformer to the case when the transformers are operating under arduous mains (line) conditions with high levels of asymmetric mains (line) distortion.
