NAD is a brand that specializes in high-fidelity audio equipment and electronics.

The NAD 214 is a power amplifier that combines a straightforward design with solid performance features. It typically includes a toroidal transformer and a capacitor bank that contribute to its robust audio output. However, it is known to have some issues such as susceptibility to bad solder joints, oxidized print connectors, and problems with its speaker relay. The main power supply capacitors in the 214 are considered undersized, particularly under high-volume conditions, leading to potential bass response issues. Upgrades and repairs are common among enthusiasts, including replacing electrolytic capacitors with higher temperature-rated units and increasing the overall capacitance for improved performance. Adjustments to the idle current may also be required to ensure optimal operation. Despite these challenges, many users find the 214 capable of delivering high-quality sound after such modifications.
