At Norma we are convinced that the influence of audio electronics on the outcome of audio reproduction is much greater than commonly assumed. Listening to a NORMA product can clarify this concept better than words, taking you closer than ever to live listening. The sound of Norma products is unique, representing a synthesis of parameters which previously have conflicted with each other. Dynamics, speed, and absolute transparency are combined with extraordinary musicality and a total lack of listening fatigue, leaving space only for pure listening pleasure.
