Ianus Geminae Power Amplifier

Aries Cerat first flagship amplifier in the Ianus Series

The Geminae harmonic distortion distribution and profile are indistinguishable from that of a SOTA Single Ended design, though the level of distortions are much lower, and output impedance is 100 times lower. This is part of it’s sonic signature and why is retains much of the magic you hear in SOTA SET amplifiers.

The Geminae is heavily biased at 12 Amperes idle (idle current is user adjustable),and its Output Transformer-less (OTL) TriodeFet output stage is working as a floating circlotron. The topology belongs to the Circlotron-esque family, but vastly improved in terms of distortion, output impedance and reliability.
