C 700
BluOS Streaming Amplifier
 
The way people discover and experience music has shifted profoundly. Today’s listeners can stream music from vast catalogues over the Internet, often with better sound quality than discs can deliver. To simplify music selection, streaming services offer discovery tools like curated playlists and recommendation engines. Wireless multi-room audio lets listeners enjoy music throughout their homes. The NAD C 700 BluOS Streaming Amplifier is a compact, “just add speakers” solution that embraces all the possibilities of the streaming age, offering state-of-the-art amplification that will transport you to your favourite musical destination.
 
A Feast for the Senses
The C 700 BluOS Streaming Amplifier was designed for the streaming age. Connect your speakers, then use the intuitive BluOS app on your smartphone, tablet, PC, or Mac to select the music you want to hear. It will sound glorious.
Through its HybridDigital UcD output stage, the C 700 can deliver 2×80 watts of continuous power and 2×120 watts of instantaneous power, for effortless reproduction of musical transients. NAD’s highly efficient HybridDigital UcD amplifier design is renowned for ultra-low noise and distortion through the entire audioband, regardless of the loudspeaker load.
Thanks to its elegant, minimalist design and premium materials, the C 700 will engage all your senses — not just hearing, but sight and touch as well. The amplifier is housed in a solid aluminum case, with a smooth glass front panel and 5″ high-definition colour display that shows album art, track progress, and system settings.
 
Following menus on the C 700’s colour display, you can adjust amplifier settings with the control knob and navigation buttons on the front panel. And the C 700 can learn commands from your favourite remote control.
 
A Modern Classic
With built-in Ethernet and Wi-Fi, and a network streamer based on the rich, robust BluOS software platform, the C 700 has everything you need to play music through your favourite speakers. Using the BluOS Controller app, you can cue up music from dozens of different streaming and Web radio services, or play music stored on an external drive connected to the C 700’s USB port.
 
Like all BluOS-enabled components, the C 700 supports high-resolution audio to 24-bit/192kHz, and has full MQA decoding and rendering capability. With these features, you can enjoy lossless and high-resolution audio from services such as Amazon Music Ultra HD, Deezer, Qobuz, and Tidal.
 
Well Connected
The C 700 has two pairs of RCA analog inputs, as well as coaxial and optical digital inputs, for connecting disc players, game consoles, media adapters, and other components. There’s also an HDMI-eARC port for connecting an HDTV with HDMI-ARC support. This allows the C 700’s volume setting to be adjusted from the TV’s remote.
