Enrico believes there is proof. But you need educated ears. It took him seven years and a concentrated R&D project started in 1991 to quantify how hifi gear compromises signal purity. Enrico’s company Opal began manufacturing Norma gear in 1997 but had already built measurement equipment to have him well familiar with the necessary tools: Living and being headquartered in Cremona influenced me. Our city is steeped in music and musical instruments.
Think Monteverdi, Ponchielli, Giuseppe Verdi, the master violins of Stradivarius, Amati and Guarneri. They left a great legacy to our school of violin making and the university’s music faculty. I fondly remember student competitions to insure the few free subscriptions our school provided for concerts at the Teatro Ponchielli. The human voice and song are one of my greatest passions. Listened to attentively, the correct reproduction of the human voice is one of the most difficult tasks.
If the recording quality allows, the micro/macro dynamics of a beautiful voice are incredible as are the richness of detail, expressive nuances and delivery refinement. And unlike other musical instruments the human voice is known to all. This enables immediate comparison. It’s why I often use the human voice in the development of Norma gear.
