Aries Cerat Ianus Protos Amplifier

TriodeFet technology is a proprietary design that combines the sonic characteristics of vacuum tubes with the power and stability of solid-state components. It allows the amplifier to maintain a pure, direct signal path while delivering the musicality and harmonic richness typically associated with high-end tube gear.

While 20 watts may seem modest, the Ianus Protos operates in pure Class A, which provides significant current and control. It is best suited for high-sensitivity speakers or medium-efficiency designs in average-sized rooms, where its focus on fidelity and dynamics can truly shine.

Separating the power supply from the main amplifier chassis isolates sensitive audio circuitry from electromagnetic interference and mechanical vibrations generated by the power transformers. This design choice ensures a cleaner signal path and a lower noise floor for improved audio clarity.

Unlike standard potentiometers that can degrade the signal over time, this relay-switched resistor ladder ensures perfect channel balance and transparency at every volume level. It provides precise, repeatable adjustments that do not color or distort the audio signal.

Yes, the unit includes a dedicated 4-pin XLR headphone output designed to leverage the amplifier's high-quality output stage. It is engineered to drive demanding headphones with the same sonic signature and refinement as your main speaker system.

The main unit is substantial, weighing 60kg, so you will need a sturdy, dedicated equipment rack or platform capable of supporting its weight and dimensions. Additionally, ensure there is adequate ventilation around the chassis, as Class A amplifiers naturally generate heat during operation.
