NAD C 359S Integrated BluOS Streaming Amplifier

NAD C 359S — A Classic Series Amplifier With Streaming Built In

The C 359S brings the direct, hands-on feel of NAD’s Classic Series into a modern music system. You get physical buttons and rotary controls, with no large display or menus to navigate. Pick a source, set the volume and play.

Behind that simple front panel are Class AB amplification, BluOS streaming, HDMI eARC, aptX HD Bluetooth and a phono input. It is one box that covers records, streaming and your TV, so a small system can start with a single component and grow from there.

Class AB Power With a Modern Supply

NAD rates the C 359S at 2 x 70 watts continuous into 8 ohms and 2 x 120 watts into 4 ohms. IHF dynamic power is 76 watts into 8 ohms and 144 watts into 4. Its high-current, low-noise switch-mode power supply draws on NAD’s Class D development work.

Peak output current exceeds 20 amps, and damping factor exceeds 210. That current reserve helps the amplifier keep control of a speaker as the load changes, and it is why the 4-ohm rating climbs so far above the 8-ohm figure.

BluOS Streaming and Multi-Room

BluOS built-in streams high-resolution music up to 24-bit/192 kHz, plus internet radio. You control it from the free BluOS Controller app, and presets on the included IR remote recall favorite stations. It also joins other BluOS players around the home for multi-room listening.

A Better Approach to Bass

Add a subwoofer, and optional high-pass filtering can steer low bass away from your main speakers. NAD says this can improve clarity, imaging and headroom, so speakers and sub work better together.

Who Is This Integrated Amplifier Best For?

• You like real knobs and buttons — pick a source, set the volume, and play, with no menus in the way
• You want TV sound through your hi-fi — HDMI eARC connects a compatible TV directly
• You stream and play records — BluOS and a phono input live in the same box
• You plan to add a subwoofer — high-pass filtering lets the sub take over the deepest bass
• You want a big screen or wireless headphones — this is not the one, since it has no large display and its Bluetooth only receives

How Does It Connect to Your System?

Connect your speakers, then your sources. A turntable goes to the phono input, a TV to HDMI eARC, and other gear to the analog or optical inputs. A subwoofer connects to the sub output.

Join your network with Gigabit Ethernet or Wi-Fi 5, then set up streaming in the free BluOS Controller app. Pair a phone over Bluetooth if you like, and plug wired headphones into the dedicated output for private listening.

An IR remote is included. The C 359S also works with Control4, Crestron, ELAN, Lutron, Push, Roon, RTI and URC. It is a two-channel amplifier for passive speakers, not a surround receiver.

Pairs Well With

Building around the C 359S? Here are some good companions:

• Bookshelf speakers that suit 70 watts per channel
• Subwoofers to put the high-pass filtering to work
• Turntables for the built-in phono input
• Headphones for the dedicated headphone output

Frequently Asked Questions

How much power does the C 359S deliver?

NAD rates it at 2 x 70 watts continuous into 8 ohms and 2 x 120 watts into 4 ohms. IHF dynamic power is 76 watts into 8 ohms and 144 watts into 4.

NAD lists BluOS as built-in, so there is no module to buy. Streaming, internet radio and multi-room all work through the free BluOS Controller app, over Ethernet or Wi-Fi.

Can I connect my TV?

Yes. HDMI eARC connects a compatible TV directly to the amplifier, so TV sound plays through your speakers over a single cable.

Can it send audio to Bluetooth headphones?

Wired headphones are the way to go. NAD lists its aptX HD Bluetooth in receive mode only, so use the dedicated headphone output for private listening.

Does it work with Roon?

NAD lists Roon among its integration partners, alongside Control4, Crestron, ELAN, Lutron, Push, RTI and URC.

What warranty does it carry?

NAD covers the C 359S with a 2-year parts and labor warranty.
