Unico Due Amplifier From Unison Research

The Unico Due replaces the long-standing Unico Secondo in the line but brings new features to the range while also drawing inspiration from the Unico 90 design

The electronic circuitry of the Unico Due has been completely redesigned from the ground-up. By working to the same brief as previous Unico models, Unison Research have introduced changes in the circuitry, the power supply method, the pre-amp stage, the power amp stage and with the variety of settings and inputs.

All based on 105μm tracks, the circuit board is fed by a power supply method that features a specially designed encapsulated transformer. The heart of the preamplifier stage is based around two ECC83 double triodes (one per channel). Configured as a gain stage followed by a cathode-follower, the circuit’s low output impedance drives the power stage.  The power amplifier stage itself features MOSFET transistors resulting in 100W per-channel output (8 Ohms).

Including a built-in USB DAC and phono stage, the USB input features an ESS Sabre DAC ES9018K2M with jitter eliminator circuit, offering support for audio files up-to 32bit/384kHz PCM and DSD256. The integrated phono stage module is pre-set to accept Moving Magnet cartridges but can be modified by a service engineer to cater for Moving Coil devices. Additionally, the Unico Due has settings for AV passthrough, subwoofer output, DAC output, a Tape loop and to adjust channel balance. Price is £2,500.
