Unison Unico Due – 100W Stereo Integrated DAC Amplifier

Unison Unico Due is the 100W integrated stereo amplifier with hybrid class A circuitry. The Italian brand has integrated into a single electronics with an elegant chassis , in addition to two ECC83 valves in the pre-amplification stage and a dynamic class A MOSFET in the output section, a very high-performance ESS Sabre DAC that supports files up to 32 bit/384 kHz PCM and DSD256.

First of all, the power supply circuits have been enhanced , significantly increasing the capacity of the capacitor bank. Furthermore, as in the entire Unico line, a key element for power supply efficiency is the use of a high-quality toroidal transformer, specially designed, shielded and encapsulated.

The new power distribution system at the output stage combines intelligent space optimization with optimal circuit design.

The heart of the pre-amplification stage has also been improved: it is now based on two ECC83 double triodes (one per channel) in pure class A, specially selected after numerous hours of testing in Unison Research 's in-house listening room. Its extremely low output impedance levels simultaneously ensure minimal electrical interference. The power stage also features an implementation, specifically of MOSFET transistors, also in dynamic class A, capable of delivering an output of 100 W per channel into 8 Ω .

This Unico Due, like the entire line, fully respects the philosophy of founder Giovanni Maria Sacchetti , integrating the preamplification, power, and conversion sections into a single electronics. This approach clearly saves space but also resources . Last but perhaps most importantly, operating in this way allows for the signal path to be reduced to a minimum and delivers a homogeneous timbre . Obviously, to be able to undertake this type of choice, the company must demonstrate extensive experience in design and construction, to avoid the risk of falling victim to the much-feared interference.

Unison Unico Due: Hybrid & Digital

The hybrid design of this Unison Unico Due aims to offer the user the best of both worlds: the sweet, smooth, and musical character of valves , thanks to a double ECC83 triode per channel in the preamp stage, and excellent driving capacity thanks to a MOSFET-based power supply. The Italian company for this integrated amplifier declares 100 W per channel into 8 ohms. In short: easy to use, fully compatible with a very wide range of speaker types, while maintaining excellent value for money. In short, it respects all the noble objectives on which this high-end range with hybrid valve architecture is based.
