NAD Electronics is a hi-fi and home theatre audio brand founded in 1972 by Marty Borish and engineer Bjorn Erik Edvardsen. The name is an acronym for New Acoustic Dimension, and the company was established with the goal of delivering high-performance audio at accessible prices, with a design philosophy that strips away superfluous features in favor of sound quality. Originally based in London, NAD is now headquartered in Canada as part of the Lenbrook Group of Companies.

The brand is best known for the NAD 3020 integrated amplifier, widely regarded as one of the best-selling hi-fi amplifiers ever made and a benchmark of affordable audiophile gear. Other notable products include the 6100 Dolby C cassette deck, the 5200 CD player, and the M2 Direct Digital amplifier. NAD's product range spans the entry-level Classic Series, the flagship Masters Series, and a Custom Install Series built around the BluOS wireless multi-room streaming platform.

NAD's engineering is associated with proprietary technologies such as Modular Design Construction (MDC), HybridDigital amplification, and DirectDigital signal processing. The brand's catalog covers integrated amplifiers, streaming amplifiers, preamplifiers, power amplifiers, AV receivers, network players, and disc players aimed primarily at home stereo and home theatre listeners rather than musicians or studios.

NAD has 4 products cataloged on Equipboard, including Power Amplifiers and Headphones & In-Ear Monitors. Their gear is featured by 1 artist, with the strongest followings in Electronic. Notable users include Dodge & Fuski.
