Familiar by Design

The C 359S stays true to the straightforward experience that has defined NAD integrated amplifiers for generations. Select a source, set the volume and settle into the music, with essential functions always close at hand. There’s no large display or menu-driven interface to navigate, yet behind that simplicity is a thoroughly modern amplifier with streaming, digital connectivity and flexible system integration. It’s a familiar approach to hi-fi, thoughtfully updated for how people listen today.

Engineered to Deliver

The C 359S takes a modern approach to proven Class AB amplification. Its high-current, low-noise switch-mode power supply draws on NAD’s Class D development expertise, providing clean, stable energy that responds effortlessly to musical demands. Delivering 2 × 70 watts continuously into 8 ohms and 2 × 120 watts into 4 ohms, the C 359S has the drive and composure to bring clarity, dynamics and control 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, making it easy to explore favourite albums, discover new music or tune into familiar stations. The intuitive BluOS Controller app keeps listening close at hand, while presets on the included IR remote provide quick access to preferred stations. Multi-room capability extends the experience to compatible BluOS players throughout the home, bringing more ways to enjoy music while preserving the simplicity that defines the C 359S.

Made for Every Source

From vinyl and digital sources to wireless listening and TV sound, the C 359S makes it easy to bring more of what you enjoy into one system. HDMI eARC connects a compatible TV directly to the amplifier, while Bluetooth aptX HD offers convenient wireless listening. Phono, analogue and optical inputs welcome traditional source components, giving the C 359S the versatility to grow with the way you listen.

A Better Approach to Bass

Adding a subwoofer can do more than extend bass response. With optional high-pass filtering, the C 359S can redirect low frequencies away from the main speakers, allowing them to focus on the range they handle best. This can improve clarity, imaging and available headroom while helping the speakers and subwoofer work more effectively together. It’s a thoughtful approach to 2.1 integration that can elevate performance across the entire system.
