The Unico Secondo exemplifies the outstanding level of knowledge and experience that Italian hifi manufacturers Unison Research have to offer, specifically in designing and constructing audiophile grade hybrid amplifiers. Based on the success of its predecessors, the Unico Secondo features some similarities with other Unison Research models, while additional and newly developed features and functions allow the unit to sit in its own league.
One such improvement is the upgraded power supply circuits, with an additional secondary winding in the power supply transformer. This means that power dissipation is reduced, while the overall reliability of the amplifier is increased. The pre-amplification section, as well as the driver stages, are based on the technology designs used in the revered Unico SE and Unico 200 models, although they have been developed and enhanced further before being placed into the Unico Secondo.
The Unico Secondo uses two high-quality ECC83 (12AX7) valves to bring the iconic Unison Research tube sound to the performance, resulting in a truly warm and musically engaging sonic experience.
RCA inputs, as well as a balanced XLR input are catered for on the rear panel, as well as an MM/MC phono input meaning that both higher end source components and turntables are directly compatible with the Unico Secondo, without the need for an external phono stage. A Tape Output and low-impedance Subwoofer out means integrating a headphone amplifier or expanding your system into a 2.1 channel set-up is done with ease and without compromising on quality.
