NAD C 3030S Stereo Amplifier with BluOS

The NAD C 3030S stereo integrated amplifier combines what many modern components have lost with what today's music systems require. It stands for authentic hi-fi sound, intuitive operation, and a design that consciously references the brand's roots. Analog VU meters, the gently curved front panel, and the classic NAD logo evoke the early years – not nostalgically, but with conviction. An amplifier for people who want to not just hear music, but experience it.

Musical performance with NAD DNA

With 50 watts per channel, the C 3030S delivers precisely the controlled, authoritative power for which NAD's Classic series is known. The sound is clear, dynamic, and free of artificiality. Vocals sound natural, instruments retain their presence, and the bass remains precise and defined. The sound signature is balanced and suitable for extended listening sessions – pleasantly warm without sacrificing resolution or transparency.

The focus is consistently on musicality. The C 3030S doesn't play spectacularly, but convincingly. That is precisely its strength.

BluOS – Streaming without detours

With integrated BluOS, the C 3030S becomes a fully-fledged streaming hub. This proven platform allows access to numerous streaming services such as Spotify, TIDAL, Qobuz, and Deezer, as well as your own music library on your home network. Hi-Res Audio and multi-room applications are supported as standard.

Control your music conveniently via smartphone, tablet, or desktop using the BluOS Controller app. The user interface is clearly structured, responsive, and focused on the essentials. Selecting music, grouping rooms, managing playlists – everything is intuitive and free of technical hurdles. Modern functionality that deliberately takes a backseat, keeping the focus on the listening experience.

Connectivity diversity with foresight

The NAD C 3030S is equally well-suited for classic and modern setups. Its well-designed connectivity options allow for seamless integration into a wide variety of listening environments.

An MM phono input allows you to connect your turntable directly. HDMI eARC lets you connect your TV, significantly improving the quality of your TV sound. Optical and analog line inputs are available for other digital and traditional sources. Bluetooth adds wireless streaming capability, while a subwoofer output with an optional 80 Hz high-pass filter offers additional flexibility for system tuning. A headphone output allows for undisturbed listening in quiet moments.

Compact, high-quality, timeless

Despite its extensive features, the C 3030S remains pleasantly compact. Its proportions are well-balanced, the housing is of high-quality construction, and the design is deliberately understated. Whether in a hi-fi rack, on a sideboard, or in media furniture – the amplifier blends effortlessly into both modern and retro-inspired living spaces. Installation is straightforward, and daily use is intuitive.
