Know before you buy
The Unico 150 uses a Pure Class A tube stage for the input and driver sections to provide the warmth and harmonic richness associated with tubes, while the Class AB MOSFET output stage ensures the power and control needed for demanding speakers.
No, the Unico 150 is a pure analog integrated amplifier. It does not feature an internal digital-to-analog converter, nor does it come with a remote control, keeping the signal path focused entirely on analog performance.
Yes, the amplifier is equipped with six line inputs, including balanced XLR connections and standard RCA inputs, allowing for flexible integration with a wide variety of high-end audio sources.
Yes, the Unico 150 supports bi-wiring, which allows you to connect the high and low-frequency sections of your speakers separately for potentially improved clarity and imaging.
The Unico 150 delivers 150 watts per channel into 8 ohms and increases to 220 watts per channel into 4 ohms, providing ample headroom to drive most high-fidelity speaker systems with ease.
Given its weight of 25 kg and the heat generated by the Class A tube stages and robust MOSFET output, it is essential to place the unit on a sturdy, level surface with plenty of open space around it to ensure proper airflow.
