NAD Great Sounding 20w RMS Integrated Amplifier 310

The NAD 310 is a compact integrated amplifier produced from the mid-1990s, embodying NAD’s “Super Simple” design philosophy. Despite its modest rating of 20 watts per channel into 8Ω, it features a robust toroidal transformer and high-current capability, allowing it to drive demanding loudspeakers with authority. Specifications include 20Hz–20kHz frequency response, <0.05% THD, damping factor above 100, signal-to-noise ratio of 106dB, and five line-level inputs.

Sonically, the NAD 310 has earned a reputation as one of the hidden gems among integrated amplifiers. Owners and reviewers consistently praise its warm, musical presentation, excellent tonal balance, and bass performance that belies its power rating. Thanks to its unusual hybrid MOSFET/bipolar output stage and generous current reserves, many listeners feel it performs more like a 50W amplifier.
