NAD C 359S & C 569
NAD has expanded its Classic Series with two new components: the C 359S integrated amplifier and C 569 CD player. The two products follow a familiar NAD formula on the outside, but combine it with updated streaming, digital processing and system-integration features.
The C 359S pairs Class AB amplification with built-in BluOS, HDMI eARC and subwoofer management, while the C 569 is a dedicated CD player using modern digital processing and ESS Sabre conversion.
C 359S Returns to Class AB
One of the most interesting aspects of the C 359S is its use of Class AB amplification.
Recent NAD Classic Series models such as the C 3050, C 379, C 389 and C 399 have leaned heavily on Class D technology. The C 359S takes a different route, delivering 70 watts per channel into 8 ohms and 120 watts per channel into 4 ohms from a Class AB output stage.
That does not mean NAD has returned to a fully traditional power-supply design. The amplifier uses a high-current, low-noise switch-mode power supply derived from technologies developed for the company’s higher-end Masters Series.
In other words, the output stage is Class AB, while the power supply remains modern and compact.
BluOS, HDMI eARC and Phono in One Chassis
The C 359S includes BluOS as standard, allowing it to function as a complete network streaming amplifier without an external streamer.
It also supports HDMI eARC for direct TV connection, aptX HD Bluetooth and a phono input.
That makes the C 359S more than a conventional integrated amplifier. It can act as a combined streaming hub, DAC and TV-audio interface while retaining traditional analogue connectivity and front-panel controls.
NAD has also kept a physical headphone output and a conventional remote-control interface, maintaining the straightforward usability associated with the Classic Series.
Proper Bass Management for 2.1 Systems
Another notable feature is the C 359S’s subwoofer integration.
Rather than simply offering a subwoofer output, NAD also provides an optional high-pass filter for the main loudspeakers.
That allows low frequencies to be redirected to the subwoofer while reducing the workload on the main speakers and amplifier.
For users building a compact 2.1-channel system around bookshelf speakers, that can make integration considerably more flexible than a basic line-level subwoofer output.
C 569 Brings New Digital Processing to CD Playback
The C 569 is positioned between the C 538 and C 589 in NAD’s CD-player lineup.
It uses DDH, or Dynamic Digital Headroom, to reduce the risk of intersample clipping during digital processing, while QRONO d2a is designed to improve time-domain behaviour and digital filtering.
The DAC section uses an ESS Sabre converter, with revised analogue output and power-supply sections.
Digital outputs are also provided, allowing the C 569 to be used as a transport with an external DAC.
NAD describes the player as part of its “Music First” approach, prioritising tonal balance and long-term listenability rather than simply chasing higher numerical specifications.
Streaming and Physical Media Side by Side
Taken together, the C 359S and C 569 reveal how NAD is approaching the modern Classic Series.
On one side, the C 359S integrates BluOS, HDMI and wireless connectivity into a traditional stereo amplifier. On the other, the company is still investing in a dedicated CD player with updated digital processing.
That combination reflects the reality of many current hi-fi systems, where streaming and physical media are not necessarily competing formats.
The C 359S is a modern network amplifier with a traditional Class AB output stage, while the C 569 brings newer digital technology to a familiar physical format.
