Italian audio label Unison Research (founded in 1987), Is not only famous for tube amplifiers, but they also like to use Italian carpentry on the tube cabinet body. Therefore, when Unison Research''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s tube machine operates, its streamlined metal parts reflect the red light of the vacuum tube. The streamlined panel created brings the dual enjoyment of hearing and vision, and also gives Unison Research a valuable impression of tube amplifiers. However, in recent years, the audio market has gradually shrunk, and the listening habits of young people have been very different from those of previous generations. Many Hi-End labels have launched transformational works in order to attract the attention of young people. Unison Research is no exception. Since 2000, they have invited Padova, Italy(Padua)Professor Leopoldo Rossetto from the university participated in the development plan of the "Unico" series. In addition to launching multiple amplifiers with a hybrid design of tube and crystal, but also considering the current situation of multiple music formats in the market, launching a combination of CD player, USB DAC and wireless Bluetooth digital source equipment.

Including this "simple phono" phono amplifier, which is positioned in the mid-to-high-end market. It uses 3 ECC83 tubes for amplification and supports MM and MC phono input. There are two sets of micro-selection switches on the back of the machine, which can conveniently set special MC impedance range, MM capacitance adjustment, different magnification and other parameters according to different input lines and the input of each group of phonographs, so as to get closer to the design accuracy Sound performance. The first-class circuit design used in this machine is the crystallization of Unison Research’s accumulated vacuum tube technology for many years. The components used in the system are matched by manual inspection and are suitable. If the specifications of the products on the market cannot meet the needs, Unison Research It is even more cost-effective and self-made, all kinds of strict requirements are only to achieve accurate signal transmission, and good stability. The internal printed circuit board circuit is made of high-cost pure silver material. The solder used for component soldering is also a product with a very high silver content, which is indeed close to the point of demanding sound quality.
