Unison Research Unico Secundo Integrated Amplifier
Excellent condition with original packaging.
Unison Research Unico Secondo Integrated Amplifier draws on the extensive knowledge and experience of the brand's technical team in the field of audiophile hybrid amplifiers.
Drawing on the success of previous models, Seconda also carves its own niche by implementing new advancements. One main improvement is to the power supply circuits which now have a secondary winding in the transformer effectively reducing power dissipation and increasing overall reliability.
Based on the coveted Unico SE and 200 models, the preamp and driver stages are further refined through in-depth analysis, extensive technical measuring and long listening sessions. The use of two high-quality ECC83 (12AX7) valves brings the iconic Unison Research tube sound to the performance.
Secondo has been carefully and thoroughly restyled while retaining the distinctive elements of the Unico Series. The front panel has a greater height than the Unico Nuovo and Primo and the casework is made from a brushed anodised aluminium cover giving a contemporary and more aesthetically pleasing look.
Unico Secondo can easily be integrated into a wide range of premium quality hi-fi systems. Together with the usual Line (RCA) inputs, it also boasts a balanced XLR input for higher-end sources. It also benefits from a built-in MM/MC phono stage for easy turntable connection.
Expand to 2.1
The Tape and low-impedance Subwoofer output enable integration of a dedicated headphone amplifier and expand your listening experience with a 2.1 channel speaker system. The supplied RC2 remote control adds convenience when controlling the unit from your listening position.
The aluminium front panel undergoes a new sandblasting and anodising process. Sandblasting hammers the aluminium plate with microscopic ceramic balls at room temperature for a homogeneous and opaque finish. Anodising facilitates the growth of a thin aluminium oxide film on the surface for enhanced mechanical resistance and robustness.
