The UNO SD's appearance was stunning. The review samples' cabinets were finished in an attractive piano-black lacquer. This lacquer, says Avantgarde, is reinforced with carbon fiber inserts. Besides piano-black, the cabinet is also available white satin, tiger rosewood, and zebrano (zebra wood). The two horns on the UNO SD art are available in 12 different colors. The high gloss color of the horns on the review sample was a high-gloss grey that Avantgarde calls Andromeda.
