Norma is based in Cremona, a place where music has always played an important role. Cremona is the home of Monteverdi, Ponchielli, Stradivari, Amati and many other artists. For more than 20 years Norma has been involved in the study and implementation of sophisticated audio amplifiers. Technical skill and musical sensitivity must be merged together, in the same way in which the best musical instruments are made.
