Aethos integrated amplifier from Rega

This new design delivers 125W per channel into 8 Ohms. The Aethos is a dual mono design using a custom wound toroidal transformer and regulated supplies

The pre-amplifier stage uses class-A circuitry throughout.

A switchable direct input and preamplifier output, enables the new Aethos amplifier to be used in a wide combination of systems.

This is a fully discrete FET based line amplifier with polypropylene capacitors, K-Power reservoir capacitors, power amplifier regulated supply and a high current output stage.

It comprises of four 160W Sanken output transistors per channel.

The Aethos uses a combined feedback and passive volume control plus line amplifier.

This was originally developed for the Elex-R.

The power amplifier used in the Aethos is an improved higher power version of the power amplifier used in the Elicit-R and Elex-R.

It is based around two complementary pairs of 160W Sanken Darlington output transistors.

By combining the low impedance driver with the Sanken Darlington transistors (with their imbedded thermal bias network running at a lower standing current), this combination forms a complementary emitter follower emulating Class-A conditions.

Two complete output stages are run in parallel, this includes the output transistors, bias network and pre-diver transistor. 

Spanning 433 x 95 x 360, it weighs 17.5kg and is priced at £2,999.

    Hi Paul, have you heard the new Rega Aethos yet? Will be interesting to compare it with the new Naim SuperNait 3. My money is on the Rega (maybe literally!).

      Not yet, Ed – I’ve only just done the news item 🙂 I’m sure it will be worth a demo.
