NAD
The 3020 — the little amp that conquered the world
History
NAD (New Acoustic Dimension) was founded in London, England in 1972 by Dr. Martin Borish, an engineer who had previously worked at Harman Kardon. Borish believed that the hi-fi industry had lost its way, focusing on specifications and features rather than musical enjoyment.
NAD's philosophy was revolutionary: focus on the aspects of design that affect musical performance while eliminating expensive cosmetic features and unnecessary functions. This "music first" approach would define the company.
The 3020 integrated amplifier (1978) became NAD's breakthrough product and one of the best-selling hi-fi components in history. With just 20 watts per channel, the 3020 outperformed amplifiers rated at 100+ watts thanks to its innovative "Soft Clipping" circuit and ability to deliver high current into difficult speaker loads.
The 1980s saw NAD expand its range with the 3020A, 3020B, 3020E, and subsequent models. The company also introduced receivers, CD players, and speakers, all following the same value-oriented philosophy.
In 1991, NAD was acquired by AudioNord, a Danish company. The brand continued to produce well-regarded electronics including the C series components. NAD pioneered digital amplification with the M2 Direct Digital amplifier in 2010.
