Unison Research Unico Pre V2 and Unico DM V2 Hybrid Dual-Mono Preamplifier and Power Amplifier Introduced

The power amplifier extends this pragmatism. Fully separated power supplies and potted transformers are not just about channel separation on paper, but about controlling electromagnetic behavior under dynamic load—something that becomes critical when the output stage is asked to deliver high current swings into complex loudspeaker impedances. The new ASHA topology can be read as Unison’s answer to the perennial Class A versus AB debate: instead of chasing bias extremes, it aims for distortion behavior that remains predictable as output increases. From an engineering standpoint, maintaining a consistent distortion profile into real‑world loads is often more audible than chasing vanishingly low figures at one operating point, and this is where the hybrid input stage plays a stabilizing role before the MOSFET array takes over.

Taken together, the Pre V2 and DM V2 feel voiced as a system for listeners who value control and tonal density over overt warmth. The bridgeable configuration of the power amp hints at scalability rather than excess, allowing the architecture to adapt as systems grow more ambitious. Compared to earlier Unico generations, the emphasis has shifted from “tube character with power” to a more disciplined hybrid ethos—one that treats tubes as precision devices rather than seasoning. For an Italian manufacturer long associated with expressive sound, this quieter, more technical confidence may be the most significant evolution of all.
