Unison Research Unico Secondo Integrated

Like any self-respecting new heir to the throne of high quality integrated amplifiers, the Unico Secondo aims to collect and concentrate all of our experience gained in the design and production of its predecessors. A result in the endless quest for the highest standards of quality, the Secondo presents a new aesthetic without losing those characteristics that have been appreciated worldwide. Attractive and in line with current aesthetic trends, the Secondo is made with astounding attention to detail.
