Unico Due

Unico Due is the latest amplifier from Unison Research. Unico Due benefits from Unison Research’s decades of experience in design and production technology. It maintains all the best qualities that made its predecessor a runaway success and introduces new and enhanced features.

The Unico Due is a high-performance integrated amplifier that combines a valve pre-amplifier with a solid-state output stage for a class-leading performance that draws heavy inspiration from the flagship Unico 90 and Unico 150 models.

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 generously sized 105µm tracks and using only the finest possible components, the circuit board is fed by a sophisticated power supply method that features a specially designed encapsulated transformer for increased efficiency and superlative sound. The heart of the preamplifier stage is based around two ECC83 double triodes (one per channel), which were purpose-chosen after hours of listening tests. Configured as a gain stage followed by a cathode-follower, the circuit’s low output impedance efficiently drives the power stage that follows for minimal electrical interference.

The power amplifier stage itself features a sophisticated implementation of MOSFET transistors resulting in 100W per-channel output (8Ω). The net result of which is a clean, powerful output with incredibly low levels of distortion. By reducing distortion so significantly in this stage, Unison Research have ensured that only the sonic character of the valves remain – staying true to the fundamental purpose of the Unico line.

The Unico Due stands out as a modern system hub not just thanks to its multiple line-level inputs, but also as a result of its 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 32-bit/384kHz PCM and DSD256. Elsewhere, the integrated phono stage module is pre-set to accept Moving Magnet (MM) cartridges, but can be modified by a service engineer to cater for Moving Coil (MC) devices. Additionally, the Unico Due has settings for AV passthrough, subwoofer output, DAC output, a TAPE loop and to adjust channel balance.

The Unico Due is a powerful, easy to accommodate amplifier with a wide range of features and a sonic presentation that boasts all the benefits of valve technology with none of the shortcomings.

Better Than OEM – Worth the Upgrade
Size: 1" x 1" x 1"
The K&N filter is a big step up from the standard Toyota air filters and OEM replacements. Installation was quick and easy, and the fit is perfect. I’ve noticed smoother airflow and better throttle response compared to the stock filter. The best part is that it’s washable and reusable, so it’s a long-term investment instead of constantly buying replacements. Definitely a smarter choice for anyone who wants performance and value over the typical paper filters.
