PHAETHON integrated amplifier is a unique product in many aspects. It uses many of the technical solutions developed in our Aelius monoblock amplifier and PST100mk2 preamplifier in a compact and elegant design.

PHAETHON is a hybrid line level amplifier utilizing only three active gain stages, two of them with low noise valves operating in single-ended class A fashion for the input and driver stage. It uses a transformer attenuator build in-house, embedded in the preamplifier section in a novel post attenuation technique.

The tube driver stage is coupled to the output stage with a wide bandwidth inter-stage transformer that provides perfect phase splitting for the output stage.

The output stage combined by same polarity semiconductors for both phases in a “balanced single-ended architecture” offers the flavor of pure single-ended designs with the power of push-pull designs.

There are separate power supplies for the tube and output stage utilizing five power supply inductors for low noise filtering.

All these were designed into one to operate in unison offering unmatched sound quality, making the platform of the integrated amplifier, a clear advantage.

All functions are remote controlled and are visible through a high quality LCD display with large characters so it can be read from across the room.
