“Without any doubt, the DUO MEZZO sounds effortless, extremely open and emotional touching. You must experience this by yourself, to understand. The totally unleashed dynamics are unbelievable fascinating. This turns on and gets you addicted. This explosiveness ca not be reached with any other system. The original dynamics of a symphony orchestra played through the DUO MEZZO formally outclasses other boxes. With the right music and attitude this is the topmost ever!” (HIFI EXKLUSIV, T. Frantzen, GERMANY)
