The Uniti Nova is the top all-in-one player of Naim Audio's second-generation Uniti range, designed and built by the British company in Salisbury. Network streaming, digital-to-analogue conversion, preamplification and power amplification share one case, with more inputs than the Uniti Atom and Uniti Star.
Key specs that matter
Output is 80W per channel into 8 ohms from a Class A/B amplifier. Digital inputs are two optical (up to 24-bit/96kHz), two coaxial RCA and one BNC (up to 24-bit/192kHz, with DSD64 via DoP) and HDMI ARC, plus two USB-A sockets and an SD card slot. Analogue inputs are RCA and Naim 5-pin DIN. Streamed files can be WAV up to 32-bit/384kHz, FLAC, AIFF and ALAC up to 24-bit/384kHz, and DSD64 or DSD128. Outputs are speaker terminals, an RCA sub/pre output and a 3.5mm headphone socket. Network connection is wired Ethernet or 2.4/5GHz Wi-Fi. Typical power consumption is 140W, and the chassis measures 95 x 432 x 265mm and weighs 13kg.
Engineering and use context
Naim filled the Uniti chassis with discrete components and a large toroidal transformer, and isolated the digital, analogue and amplifier circuits from each other. Finned aluminium heatsinks along the sides, a design borrowed from Naim's Statement amplification, cool the output stage without fans. Streaming covers Chromecast built-in, Apple AirPlay, TIDAL, Spotify Connect, aptX HD Bluetooth, internet radio, UPnP and Roon Ready. A large internal buffer holds several minutes of streamed audio to reduce dropouts on unstable networks. The Nova can join up to six Naim streamers in multiroom party mode, or serve up to 20,000 tracks from attached USB drives to other players on the network. On the front are a 5-inch colour display and Naim's illuminated volume control with a proximity sensor. Control is through the Naim app for iOS and Android or a Zigbee RF4CE remote, HDMI ARC takes TV sound, and new firmware is installed over the network.
Pairing
The Uniti Nova drives most stand-mount and floorstanding speakers directly. Its sub/pre output lets a subwoofer or an external Naim power amplifier be added later, following Naim's traditional upgrade path, and the DIN input suits Naim sources.
Alternatives
The Naim Uniti Star builds a CD drive into a 70W Uniti chassis with fewer inputs.
