Unico 90 is a class A 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 amplifier itself is comprised of premium quality German Mundorf componentry and an innovative, Unison Research-specific circuit to deliver a weighty, rich 160 watts for channel.

The Unico 90 is a class A hybrid integrated amplifier and offers a zero feedback performance.

Available in Black or Silver Finish.
