Rega Osiris - reference level integrated amplifier

Osiris is the culmination of over three decades of design expertise – it is Rega's most uncompromising and refined integrated amplifier. The structure is based on a dual mono architecture, with its own 400 VA toroidal transformer and massive storage capacity for each channel. This allows the amplifier to offer exceptional control, dynamics, and current delivery into all loads.

The signal path is implemented with a minimalist philosophy: only a passive Alps volume control and a single power amplifier stage ensure the shortest and most interference-free path possible. The result is a sound that is simultaneously open, rhythmic, and musical – Osiris reveals the nuances and power of music in a way that elevates it to a level of its own.

The power amplifier stage features eight 200 W Sanken transistors per channel, which, along with carefully selected components (including Nichicon audio capacitors and polypropylene capacitors), guarantee top-level performance and reliability.

The casing is made of CNC-machined solid aluminum, which also serves as an efficient heat sink. This ensures optimal temperature management and makes the structure exceptionally robust. The whole is crowned by a stylish finish and a remote control with an aluminum frame.

Osiris is handmade in England and is designed to provide a lifelong listening experience for anyone seeking the absolute pinnacle in an integrated amplifier.

What Hi-Fi? has awarded Osiris a full five stars, describing it as “one of the most impressive amplifiers on the market”. Hi-Fi Choice has honored Osiris with an Editor’s Choice award, highlighting its excellent dynamics, deep bass, and transparent treble. The Ear emphasizes Osiris's infinite stability and control even with demanding speakers.
