Unison Research Unico DM v2

The Unico DM v2 is the most significant statement Unison Research has made in the Unico line since the series began. 220 watts per channel, dual-mono throughout, with a Class A tube input stage and a new output topology that the company developed specifically for this design. It is also, unmistakably, Italian — in the way that description carries real meaning in high-end audio.

The Design

The v2 marks a deliberate shift in Unison Research's aesthetic. The 15mm solid aluminum front panel — machined, not extruded, not folded — sets the tone from the first moment you see it. The 2mm aluminum top cover wraps continuously around the enclosure for structural rigidity and visual coherence. Wooden accents remain, used sparingly now as a reference to the historic Unico logo rather than a dominant visual element. The Unison Research logo functions as the power switch. Midnight Black or Velvet Gold.

The Architecture

True dual-mono. Each channel has its own 750VA encapsulated toroidal transformer, potted and shielded against electromagnetic interference. The two channels share a chassis and nothing else of consequence — power delivery, regulation, and signal paths are fully independent. Channel separation that a shared-supply design cannot achieve.

Three amplification stages. The first is a Class A tube stage using one ECC82/12AU7 Gold Lion valve per channel. This is the tonal foundation of the amplifier — speed, fine detail, the emotional texture of the music all originate here. The second stage is solid-state, operating transparently to adapt the signal to the output. The third stage is where the DM v2 introduces A.S.H.A.

A.S.H.A. Technology

Analog Synchronized Hybrid Amplification is Unison Research's new output topology, introduced for the first time in the DM v2. It operates in Class A-AB using MOSFET output devices, delivering high power with lower distortion and better thermal behavior than conventional Class AB implementations. The bridges to 650 watts mono configuration makes the DM v2 a serious option for demanding loudspeakers in large rooms.

Press Recognition

The Unico DM v2 has been reviewed by Hi-Fi+, Hifi News, and Positive Feedback. Hi-Fi+ called it among the finest hybrid amplifiers available at any price, with particular praise for the A.S.H.A. output topology's combination of power and musicality. Hifi News noted the build quality as exceptional even by Italian high-end standards.
