Ex Display... Made in Italy... Unison Research Secondo Phono Valve Hybrid Integrated Amplifier in Silver.

The Unico Secondo draws on many years of knowledge and experience gained by Unison Research's technical team in the field of audiophile hybrid amplifiers. This new amplifier draws on the success of previous models, but also carves its own niche with the implementation of new advancements. 

The power supply circuits have been improved with the addition of a secondary winding in the power supply transformer, effectively reducing power dissipation and increasing the overall reliability of the Secondo. The pre-amplifier and driver stages are based on the designs used in the coveted Unico SE and Unico 200 models, though they've been 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.

While the Unico Secondo has undergone a careful and thorough restyling compared to previous models, it has not lost the distinctive elements of the Unico Series. The front panel has a greater height when compared to the Unico Nuovo and Primo, and the case-work is made from brushed anodized aluminum cover, which gives the amplifier a contemporary and more aesthetically pleasing look.

The Unico Secondo can easily be integrated into a wide range of premium quality hi-fi systems. Together with the usual Line (RCA) inputs, the Secondo also boasts a balanced XLR input for higher-end sources. All models sold in the UK also benefit from a built-in MM/MC phono stage for easily connecting a turntable. The Tape Output and low-impedance Subwoofer Output (which attenuates with the volume control) means you can also integrate 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 from your listening position.

The aluminium front panels on all Unico series products are clean and stylish thanks to a new sandblasting and anodizing process. The sandblasting consists of hammering the the aluminium plate with microscopic ceramic balls at room temperature to give the surface a homogeneous and opaque finish. The anodizing process facilitates the growth of a thin film of aluminium oxide on the surface, which enhances the mechanical resistance and hardness of the surface. The end-result is truly stunning to help round off this prestigious piece of equipment.
