NAD C 379 HybridDigital Amplifier with BluOS

The Streaming Module Is Already Fitted

This is the C 379 with NAD's MDC2 BluOS-D module installed from the factory. You get hi-res streaming, multi-room, and Dirac Live room correction working the day it arrives, with no slot to fill and no second purchase to make.

Underneath, it is the same amplifier. NAD's HybridDigital UcD platform delivers 80 watts per channel into 8 ohms, with IHF dynamic power of 140 watts. One MDC2 slot remains free for whatever comes next.

Every Service You Use, Through One App

BluOS reaches more than twenty streaming services along with internet radio and networked libraries. Tidal Connect, Spotify Connect, Qobuz Connect, AirPlay 2, and Roon Ready are all supported, and BluOS groups up to sixty-four zones around a house.

Wired sources are handled too. A moving-magnet phono stage takes a turntable, HDMI eARC takes the television, and optical, coaxial, and analog inputs cover the rest. Two subwoofer outputs sit beside a headphone amplifier.

Why Class D Stopped Being a Compromise

An ESS SABRE 32-bit DAC handles conversion for every digital input. Distortion stays below 0.03% from a quarter watt to 120 watts, into 8 ohms and 4 ohms alike, so the rated output is clean across its whole range rather than at one flattering point.

Damping factor comfortably exceeds 300, which is what stops a woofer from ringing on long after the note. Signal-to-noise runs better than 85dB, channel separation better than 75dB at 1kHz, and frequency response holds inside 0.3dB from 20Hz to 20kHz, which is a tight window indeed.

Let Dirac Deal With the Room

Dirac Live Limited Bandwidth comes with the BluOS module. It measures what your room does to the sound and corrects for it, which matters more in a real living room than another few watts ever will.

The MDC2 architecture is two-way, so the module works inside the signal path, not beside it. Streaming here is not a bolted-on afterthought, and a later module can replace it cleanly.

What Reviewers Are Saying

Dennis Burger reviewed the C 379 with the BluOS module fitted for SoundStage! Access on February 1, 2025, and gave it a Reviewers' Choice Award. He wrote that it "embodies the ethos of SoundStage! Access nearly perfectly."

He went further, calling the C 379 "absolutely a model for what a budget-conscious integrated amp with zero performance compromises should look like," and "the best value I've encountered in quite some time."

He named one gap plainly. "The only thing it really lacks is a USB-DAC connection, but that's par for the course with NAD." He also wished BluOS made it easier to drop a single zone out of a group.

Who Is This Streaming Amplifier Best For?

• You want streaming working out of the box — the MDC2 BluOS-D module is fitted at the factory, not sold separately.
• Your room fights you — Dirac Live room correction comes with the module.
• You run a house, not just a room — BluOS handles up to sixty-four zones from one app.
• You play vinyl and watch TV — a moving-magnet phono stage and HDMI eARC are both built in.
• You want it working the day it lands — BluOS, Dirac, HDMI eARC and two subwoofer outputs are already fitted, with nothing to add later. Pair it with one of our subwoofers and let Dirac integrate it.

How Does It Connect to Your System?

Speakers go to the binding posts, a turntable to the phono input, and the television to HDMI eARC. Optical, coaxial, and analog inputs take your other sources.

Ethernet or Wi-Fi joins the network for BluOS. Two subwoofer outputs let you run a pair properly, and headphones use the dedicated front-panel amplifier.

Then you run Dirac once and stop blaming the speakers.

Pairs Well With

Building around the C 379 with BluOS? Here are some good companions:

• Speakers: 80 watts and a damping factor over 300 grip a real pair — see our Floorstanding Speakers.
• Turntable: Put the built-in MM phono stage to work — see our Turntables.
• Subwoofers: Two independent outputs reward running a pair — see our Subwoofers.
• Headphones: The dedicated headphone amp deserves a good pair — see our Headphones.
