The Rega Osiris is the flagship solid-state integrated amplifier from the renowned British audio manufacturer Rega Research. Designed as a "no-compromise" component, it represents the absolute peak of Rega’s amplifier engineering.

Core Concept & Philosophy

Unlike typical high-end setups that rely on separate preamplifiers and power amplifiers, the Osiris packs extreme reference-grade power into a single chassis. Rega uses a minimalist topology: a passive pre-amplifier section feeding directly into a high-gain power amplifier. By eliminating unnecessary gain stages, it keeps the signal path as short and pure as possible.

Key Specifications & Performance

  • Power Output: 162 Watts per channel into 8 Ω (delivers 250 W into 4 Ω), capable of driving virtually any speaker load effortlessly.

  • Dual-Mono Architecture: Features two completely separate power supply channels, including twin custom 400 VA toroidal transformers and 40,000 µF smoothing capacitors per channel.
  • Output Stage: Utilizes eight 200W Sanken output transistors in a triple high-current configuration to handle demanding dynamic transients.
  • Frequency Response: 10 Hz to 75,000 Hz.
  • Weight: A massive 25.6 kg (56.4 lbs), built inside a custom CNC-machined aluminum chassis with massive heat sinks.
