Overview

The NAD C 359S brings familiar NAD simplicity together with contemporary performance and connectivity. Delivering 2 × 70 watts of continuous power into 8 ohms, it combines proven Class AB amplification with a high-current, low-noise switch-mode power supply for confident real-world performance. Physical controls keep operation direct and intuitive, while BluOS built-in adds high-resolution streaming and multi-room capability. HDMI eARC, Bluetooth, phono, flexible connectivity and sophisticated subwoofer integration make the C 359S a versatile centerpiece for music, TV and more.

NAD Simplicity

The C 359S preserves the Classic Series design that has long defined NAD integrated amplifiers. Physical buttons and rotary controls, together with an included IR remote, provide direct access to everyday functions without relying on a large display or menu-driven interface. Behind these familiar controls are modern capabilities including streaming, digital connectivity and flexible system integration. The result is an intuitive listening experience with the flexibility expected from a modern hi-fi system.

Modern Class AB

The C 359S pairs proven Class AB amplification with a high-current, low-noise switch-mode power supply. Drawing on NAD’s Class D development expertise, the power supply delivers clean, stable power with the responsiveness needed for musical dynamics. A modern circuit architecture keeps power conversion, signal processing and amplification carefully separated to help minimize unwanted interaction. The C 359S delivers 2 × 70 watts of continuous power into 8 ohms, rising to 2 × 120 watts into 4 ohms for greater power delivery into more demanding loudspeaker loads.

BluOS Built-In

With BluOS built-in, the C 359S provides high-resolution music streaming without the need for a separate streamer. The BluOS Controller app makes it easy to access streaming services, internet radio and music stored on a local network, all from one intuitive interface. BluOS also adds multi-room capability, allowing the C 359S to connect with compatible BluOS players throughout the home. With streaming integrated directly into the amplifier, a world of music is always within easy reach.

Versatile Connectivity

The C 359S brings a wide range of music and entertainment sources together in one system. HDMI eARC makes it easy to enjoy TV sound with the C 359S, while Bluetooth provides convenient wireless listening from compatible devices. Phono, analogue and optical inputs accommodate turntables and other traditional source components, and a dedicated headphone output provides an option for private listening. This flexibility makes it easy to enjoy everything from vinyl and CDs to TV audio and wireless music through the same amplifier.

Smarter 2.1 Integration

The C 359S takes a more considered approach to integrating a subwoofer into a stereo system. Optional high-pass filtering redirects low frequencies to the subwoofer, reducing the bass demands placed on the main speakers and amplifier. This can improve clarity, imaging and available headroom while allowing the speakers and subwoofer to work more effectively together. The result is a flexible foundation for building a capable 2.1-channel music system.
