REGA Osiris

Rega’s flagship integrated amplifier

The Osiris is the culmination of 32 years experience in solid-state amplifier development. A no compromise, super high performance, 162 W into 8 Ω (250 W, 4 Ω), 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. The Osiris is designed as the perfect partner for the rest of the reference range, such as the Isis CDP, Valve Isis CDP and Aura MC phono stage.
