Familiar by Design

The C 359S keeps the straightforward experience that has defined NAD integrated amplifiers for generations: choose a source, set the volume and enjoy the music, with all essential functions close at hand. There is no large display or menu to navigate, yet behind this simplicity is a thoroughly modern amplifier with streaming, digital connectivity and flexible system integration.

Engineered to Deliver

The C 359S takes a modern approach to proven Class AB amplification. Its high-current, low-noise switch-mode power supply builds on NAD's Class D expertise and provides clean, stable energy that responds effortlessly to musical demands. With 2 × 70 W into 8 ohms and 2 × 120 W into 4 ohms, it has the drive and control to bring clarity and dynamics to a wide range of loudspeakers.

Discover More with BluOS

BluOS built-in brings high-resolution streaming and internet radio directly to the C 359S. The intuitive BluOS Controller app keeps your music close at hand, presets on the supplied IR remote give quick access to favourite stations, and multi-room capability extends listening to other BluOS players throughout the home.

Made for Every Source

From vinyl and digital sources to wireless listening and TV sound, the C 359S brings everything into one system. HDMI eARC connects a compatible TV directly to the amplifier, Bluetooth aptX HD offers convenient wireless playback, and phono, analogue and optical inputs welcome traditional source components.

A Better Approach to Bass

With optional high-pass filtering, the C 359S can send low frequencies to a subwoofer and relieve the main speakers, letting them focus on the range they handle best. This can improve clarity, imaging and headroom, and helps speakers and subwoofer work together as a well-integrated 2.1 system.
