Unison Research Unico Primo
The Primo is a stereo integrated amplifier that offers elegant lines and details, thanks to carefully considered surface finishes and proportions. Solid construction, careful selection of components and precise assembly are part of an almost artisan approach to amplifier design, reflecting our origins in Treviso. Unison Reasearch has concentrated all of our experience, knowledge and ambition into a small amplifier—one that includes all the technology and passion that one usually finds in the finest flagship products.
Unison Research Unico Primo stereo integrated amplifier
- Hybrid Design: Combines a single ECC83 (12AX7) triode tube in the input stage with a Class A dynamic MOSFET output stage, delivering the warmth of tubes and the precision of solid-state amplification.
- Power Output: Delivers over 80W RMS per channel into 8Ω, providing ample power for a wide range of
speakers. - Frequency Response: Extends from 10Hz to 100kHz with minimal deviation, ensuring accurate reproduction across the audio spectrum.
- Low Distortion: Total Harmonic Distortion (THD) of 0.15% at 10W (1kHz), maintaining audio fidelity.
- High Signal-to-Noise Ratio: Achieves a 90dB SNR, resulting in a clean and quiet background.
- Input Options: Equipped with 5 RCA line inputs and an optional MM/MC phono stage for turntable connectivity.
