Ianus Protos Integrated Amplifier
TRIODEFET | CLASS A | 20W STEREO INTEGRATED AMPLIFIER
The Ianus Protos amplifier is not only Single Ended, it is also a Single Stage! Like the bigger Essentia model, incredibly, there is no driver stage and no input stage! However this is not just an amplifier but a complete integrated amplifier.That means that from the input to the speaker outputs, there is only one stage of amplification.
This extremely simple topology we feel is a breakthrough in amplifier design, and is an elusive design goal for many, including our lab. This feat was only possible to execute after the breakthrough of our TriodeFet technology, and now 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. All in a single stage.
The Aperio and Protos integrated amplifiers use a common circuit core but with many differences in PSU design and part design.
