About the brand
NAD's approach towards product development is equally uncommon. Its products are developed by music lovers for music lovers. It is not the company's policy to impress potential customers with figures that look good solely on paper. NAD engineers understand that technical specifications tell only half the story. Far too often there is a large discrepancy between specifications in the brochure and "real-world" performance. By studying actual listening in realistic environments and the interaction between components, NAD products achieve a level of performance far beyond that which the specifications suggest.
