You might be saying to yourself, “Another Unico? Really?” We’ve even had people complain to us that since Unico means “one,” we shouldn’t have so many Unicos in the Unison Research product line! But the simple fact is that to us, “Unico” also means “unique,” and there are no other electronics that come close to the performance, value, features and beauty of the Unico line. This is why we’re proud to introduce this newly-born Unison Research amplifier and to call it, once again, a Unico.
First of all, the Unico50 is a powerful stereo integrated amplifier that fits into a relatively compact chassis. It integrates perfectly into the latest generation of high-level Unico designs and even shares the same dimensions as the UnicoCDE and UnicoPRE. That means the Unico50 looks substantial and authoritative while still maintaining a well-proportioned and appealing look that’s easy to integrate into any type of environment.
Our design staff wasn’t scared off by the challenge of combining aesthetics and technical sophistication. First, they took the cumbersome, oversized heatsinks found in most powerful amplifiers and transformed them into distinctive black anodized side panels that are perfectly integrated into the chassis. This design increases the overall strength and sturdiness of the Unico50 chassis.
In addition, this impression of power, grace and beauty is reinforced when you pick up the Unico50 for the first time. It’s nearly as heavy as its big brother, the Unico100. This feeling of unbridled strength and finesse is further enhanced when you touch the solid aluminum knobs on the front panel for the first time. These knobs drive a couple of heavy-duty rotary encoders from ALPS which have been selected by our design team for their reliability as well as their precise and firm operation.
The following driver stage is derived from a well-known and time-tested topology designed by Unison Research. But since our technical staff is never tired of going just a little bit further with a design, they offered additional refinements that increase the inner input impedance, thereby offering a better load to the preamp stage. In this configuration, the interface parameters are the same as when you match a stand-alone preamplifier to a power amp.
Another revolutionary feature involves the power stage design: you won’t find any power
The BJTs employed are specifically designed for audio and exhibit high current capability and great reliability. A thermally-enhanced package, in conjunction with special thermal conductive insulation pads, makes them the perfect choice for such a demanding design. In order to reduce distortion introduced by inevitable dissymmetry of different devices, even if the measurements matched, we adopted a different approach by designing an uncommon topology that ensures perfect equality between the positive and negative side of the power stage mixing npn and pnp devices.
Such a refined design can only express its true potential if supported by an adequate
The Unico50 is a truly revolutionary addition to the Unico series. This new amplifier preserves all of the qualities that made the Unico series one of the most elite product lines in the world, and yet it pushes the boundaries even further by renewing the promise of an utterly exciting listening experience.
