Unison Research Unveils UNICO PRE V2 and UNICO DM V2 with Advanced Amplification Tech
Experience the warmth and clarity of Unison Research’s UNICO PRE V2 and UNICO DM V2 featuring breakthrough Analog Synchronized Hybrid Amplification.
A New Era in Hybrid Amplification
If you’ve ever been captivated by the lush sound of tube amplifiers but craved modern reliability and efficiency, Unison Research’s latest release will feel like a dream come true. The Italian audio artisans from Treviso have launched the UNICO PRE V2 preamplifier and UNICO DM V2 dual-mono power amplifier, anchored by their innovative Analog Synchronized Hybrid Amplification (A.S.H.A.) technology.

A.S.H.A. isn’t just a fancy acronym—it’s a fresh take on hybrid amp design that shakes up the game. At its core, it introduces a proprietary Class A-AB power stage topology. This clever Leader-follower configuration manages to fuse the creamy harmonic richness and musicality of pure Class A with the hard-hitting efficiency and stability of Class AB designs. The result? Amplifiers that sing with tonal naturalness and flow effortlessly, yet never lose grip on the dynamic demands of contemporary loudspeakers.
UNICO PRE V2: Pure Transparency Meets Tubed Warmth
Stepping into the spotlight, the UNICO PRE V2 is a fully balanced hybrid preamplifier that marries a Class A tube input stage with a meticulously crafted solid-state Pure Class A section. What’s truly refreshing here is the absence of negative feedback, a feature that many audiophiles will appreciate. This design choice ensures the music is presented with astonishing transparency, greater linearity, and enhanced signal coherence.
Listening through the UNICO PRE V2, you’re treated to a sound full of depth and texture—music that feels real and alive, escaping the sterile confines of some modern electronics.
UNICO DM V2: The Dual-Mono Powerhouse
Complementing the PRE V2 is the UNICO DM V2, a true dual-mono power amplifier designed from the ground up to deliver uncompromising performance. Each channel boasts independent circuitry and dedicated power supplies, which means pristine channel separation and minimal interference.
Drawing from the A.S.H.A. technology, the DM V2's Class A-AB configuration grants it the best of both worlds: the warmth and spatial richness of Class A, combined with the speed, grip, and durability of Class AB. The sonic payoff? Punchy, authoritative bass, a refined midrange, and an expansive soundstage that invites you into the heart of the music.
A Harmonious Pair
When paired, the UNICO PRE V2 and UNICO DM V2 form a reference-grade amplification system that perfectly encapsulates Unison Research’s ethos—melding cutting-edge technology with an unwavering dedication to musical authenticity. Each unit is painstakingly handcrafted in Italy, showcasing the company’s steadfast commitment to high-quality engineering and artisanal craftsmanship.
This synergy invites you to rediscover your favorite records with fresh ears, brimming with nuance and emotional resonance.
