NAD C 359S combines Class AB amplification, BluOS and HDMI eARC

Catch-up — original announcement: 15 October 2026.

NAD has introduced the C 359S integrated amplifier and C 569 CD player. The amplifier combines Class AB output stages with built-in BluOS streaming and HDMI eARC for TV sound. NAD rates it at 70 watts per channel into 8 ohms.

Connections include phono, analogue and optical inputs. A subwoofer output and optional high-pass filtering let a 2.1 system relieve the main speakers of deep-bass duties. The C 569 provides a separate CD source with an ESS SABRE DAC and analogue and digital outputs.

NAD's announcement lists the amplifier as available in the US and Canada, with the CD player due in late November. Availability elsewhere needs local confirmation.

Why it matters
For a shared music-and-TV system, the C 359S brings streaming, TV audio and bass management into one amplifier. These are announced features, not an independent assessment of sound quality.

Would HDMI eARC and BluOS persuade you to consolidate separate boxes?

Depends a lot on what the "music and TV system" actually looks like in practice.

If this is a single pair of speakers in a living room doing double duty - streaming during the day, TV sound at night - then yes, eARC and BluOS in one box genuinely removes a box. You skip the soundbar-vs-stereo compromise most people end up making in that room, and the sub output with high-pass is the detail that actually matters here: your 70W into the mains isn't also trying to reproduce 40Hz, so you get more midrange headroom and can run a modest sub for the bottom octave instead of needing big floorstanders.

Where it falls apart is anything beyond 2 channels. eARC solves "TV sound," not "home theater." The moment you want a center channel for dialogue or any surrounds, you're back to a separate AVR or processor, and the C 359S either becomes redundant or gets relegated to a second zone. NAD clearly knows this - it's why they're positioning it as a 2.1 streaming amp with eARC as a bonus, not as a receiver replacement.

The thing I'd actually keep an eye on is eARC handshake behavior with whatever TV it ends up paired with. Nearly every eARC chain I've dealt with has at least one TV in it that drops the connection after a firmware update or a long standby, and when that TV is also your only source switcher, that's not a cosmetic bug - it's a "no sound at all until you unplug something" bug. BluOS itself has been solid in my experience, so that part I wouldn't worry about.

Sticking with Class AB here over Class D is the right call too, even though it costs them a bit on the spec sheet - BluOS zone switching and standby/wake cycling tend to behave more predictably on Class AB without having to carefully tune a Class D module's idle/wake states around it.
