World class hi-fi, designed and made in England since 1973, Rega produces turntables, amplifiers, loudspeakers and more.

Rega

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.

The Osiris uses a low distortion high linearity and a bandwidth common base voltage amplifier driver stage. This type of symmetrical circuit topology will provide the necessary voltage swings to enable the Osiris to drive any speaker system with the minimum of distortion. Eight Sanken 200 Watt output transistors are used in a “triple” high current output stage enabling the Osiris to drive even the most awkward of speaker systems with ease.

The cascoded differential input amplifier uses two low noise LED referenced current generators. The open & closed loop feedback levels and gain bandwidth product components are optimised to give a tight and controlled sound stage, especially at the low frequency end of the audio range. Nichicon audio grade capacitors are used in bypass and de-coupling positions. Electrolytic capacitors have been bypassed with polyester capacitors where necessary, improving on the HF performance. Low inductance film SM power resistors are used in the output stage.
