The Aethos is a no compromise product with one goal, to deliver your music as faithfully as possible. The Aethos has been built to Rega’s high standards of reliability and quality to ensure many years of musical enjoyment.
Their time, effort & money have been spent on developing the circuit and construction, utilizing the highest specification of components throughout. As part of the design they have included useful features such as the switchable direct input and preamplifier output, to enable the new Aethos amplifier to be used in a wide combination of systems. The headphone socket has been integrated such that the speaker switching is performed by the output mute relay as so not to obstruct the signal path and degrade the sound quality.
Rega has taken the design concepts underpinning the multi award winning and hugely successful Elex-R and Elicit-R and propelled the performance to the next level and beyond with a 125watt dual mono design with features such as fully discrete FET based line amplifier, polypropylene capacitors throughout the signal path, K-Power reservoir capacitors, power amplifier regulated supply and a high current output stage comprising of four 160w Sanken output transistors per channel.
This product has been designed to accompany the existing Aura MC stage and Planar 10 turntable (with Apheta 3 MC) to create a system delivering performance well beyond anything else at this price point in their view.VOLUME CONTROL AND LINE AMPLIFIER TECHNOLOGY
POWER AMPLIFIER TECHNOLOGY
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. The output amplifier used in the Aethos, was born after extensive research by our engineers to develop a low source impedance emitter follower Class-A driver stage. This is based around two complementary pairs of 160w Sanken Darlington output transistors. The technical and sonic improvement gained by the use of low impedance drivers is well known, however, it can feature high standing currents in the driver stage when using standard transistor configurations. 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 with good thermal stability and lower standing currents in the driver stage. Due to the nature of the Rega power amplifier circuit we are able to run two complete output stages in parallel, this includes the output transistors, bias network and pre diver transistor this is instead of paralleling just the output transistors as normally found. This ensures the 125 watt output is achieved with complete ease.
