Overview — The Unico 150

The Unison Research Unico 150 raises the bar in hybrid amplifier design, marrying a two-stage tube preamp (ECC83 + 6H30 triodes) operating in pure Class A with a high-current Class AB HexFET output stage. With 150 W per channel into 8 Ω (and up to 220-250 W into 4 Ω), this amplifier is built for serious speakers and listening rooms.

Featuring wide bandwidth (-1 dB from 12 Hz to 45 kHz), low feedback design (overall feedback = 0 dB), balanced XLR inputs, unbalanced RCA inputs, subwoofer output, and bi-wiring speaker terminals, the Unico 150 blends Italian craftsmanship, high-quality components, and system integration flexibility.
