Unison Research Unico DM Hybrid Dual Mono Power Amplifier

The Unison Research Unico DM is a hybrid dual-mono power amplifier available at Vinyl Sound USA Inc. in Buffalo, NY, your authorised Unison Research dealer serving Western New York and the United States. Designed as the natural partner to the Unico Pre preamplifier, the Unico DM blends a pure Class A tube input stage with a dynamic Class A MOSFET output stage, combining the harmonic character of vacuum tube amplification with the control, headroom, and reliability of a fully engineered dual-mono power stage.

Compared to the earlier Unico DM, this current version is a ground-up revision rather than a simple update, with Unison Research substantially reworking the unit's most important design parameters to deliver more robustness and more power than any previous iteration. Each channel runs its own independent dual-mono amplification path, driven by a Double tube stage (ECC82/12AU7) ahead of a Triple POWER MOSFET complementary output pair, delivering 160W RMS continuous per channel into 8 ohms in stereo mode, or 650W RMS continuous into 8 ohms when bridged to mono — enough headroom for demanding loudspeaker loads without sacrificing the natural, engaging tonal balance Unison Research amplifiers are known for.

Flexible balanced and unbalanced inputs, along with bi-wire-ready output terminals, make the Unico DM easy to integrate into most high-quality two-channel systems, not only Unison Research's own Unico line. Visit Vinyl Sound Buffalo to audition the Unico DM paired with the Unico Pre, or matched with other Unison Research preamplifiers and source components.

Frequently Asked Questions

Can the Unico DM run in mono mode?
Yes. The Unico DM is a dual-mono design that operates in stereo (160W RMS continuous per channel into 8 ohms) or can be bridged to mono for 650W RMS continuous into 8 ohms — ideal for driving demanding loudspeaker loads.

Is the Unico DM a tube or solid-state power amplifier?
It's a hybrid design: the input stage is a pure Class A double tube stage using ECC82/12AU7 valves, while the output stage is a dynamic Class A triple POWER MOSFET complementary pair.

What preamplifier pairs best with the Unico DM?
The Unico DM is designed as the ideal match for the Unison Research Unico Pre, though its balanced and unbalanced inputs let it integrate into most high-quality audio systems.

Where can I buy the Unison Research Unico DM in the US?
At Vinyl Sound USA Inc. in Buffalo, NY, the authorised Unison Research dealer for Western New York and the United States.
