The Ianus Essentia amplifier is not only Single Ended, it is also a Single Stage! Incredibly there is no driver stage and no input stage! This extremely simple topology we feel is a breakthrough in amplifier design, and is an elusive design goal for many, including our lab. It is only possible to execute now as we are finally able to use an active element that has the needed specifications for the purpose: Extremely high linearity, high voltage gain, high current gain and very high input impedance.
The Essentia, as its name suggests, consists of only one TriodeFet stage, fed directly and used as a simple Single Ended amplifier and uses the “Essence” of the Geminea technology.
The triode-like transfer curves of the TriodeFet means the Ianus Essentia sounds very much like the very best Single Ended tube amplifier. A superb midrange and treble, accurate timbre and the huge soundstage we expect from big bottle tube amplification.
In the case of the Ianus Essentia it is also able to deliver more current, and is essentially maintenance free as the internal tubes used for curve creation are rated at 10,000 hours lifespan. Its unique single stage nature means that it is as sonically transparent as it can get. The amplifier power delivery is 40W (8ohm) full class A.
