Unico 90 Hybrid BLACK

Unison Research Unico 90 Hybrid

Description

Unico 90 is a class AB hybrid integrated amplifier with zero feedback, as the most precious valve amplifiers uses only two stages. The heart of the Unico 90 circuit is found in its hybrid structure. All of the gain, and subsequently the “character” of the amp, is determined by the only tube stage made with ECC83 and ECC 81in particular multiple-parallel-totem-pole.

The Unison Research Unico 90 is a highly regarded Italian-made hybrid integrated amplifier (100W/ch into 8ohm,160W/ch into 4ohm) that combines ECC83/ECC81 tube pre-amplification with MOSFET power stages. It is praised for delivering a powerful, dynamic sound with a “tubey,” holographic midrange alongside excellent speed and control. The dual-mono design (20kg) features zero global feedback.
The Unico 90 is a fantastic choice for audiophiles seeking a high-performance, refined sound that doesn’t sacrifice power for musicality. It is particularly adept at reproducing, with precision, the smallest details in music while having the power to drive demanding loudspeakers effortlessly.
