Initially headquartered in London, UK, NAD’s growing team of engineers, led by Edvardsen, obsessively experimented and refined the electronic designs, seeking that eureka moment when they knew they had a winning design. This culminated in the ultimate reward for the engineers and the brand – the distinction of creating the best-selling hi-fi amplifier in history, the NAD 3020. This was a turning point for NAD; a point when both Edvardsen and the NAD brand developed a cult-like following that has remained loyal to NAD products and solutions ever since.
