While power amps have one simple job, it's a crucial job indeed. The power amp has to be extremely tough, yet responsive to the dynamic peaks of music and movie soundtracks.
NAD has a range of power amps to suit your home entertainment needs, from classic purist hi-fi design, to big beastly stereo/mono bridgeable behemoths, to multi-channel models for home theatre or multi-zone applications.
Power amps are the companion to your preamp/processor. It's easy to expand your system by adding a power amp to the 'Pre-Out' or Zone 2 / 3 / 4 connections of your device.
