NAD has today announced a new entry-level streaming DAC. The CS1 is both a network streamer (with dual-band wifi and Ethernet inputs) and a Bluetooth 5.0 DAC. The internal D/A converter is built around an “advanced differential digital” implementation of a Texas Instruments PCM5141 chip. It outputs via a pair of analogue RCA sockets where full MQA decoding and rendering are part of the deal.
Those already in possession of an external DAC – either fully outboard or located inside an integrated amplifier, home theatre receiver or pair of powered loudspeakers – can make use of the CS1’s coaxial and TOSLINK outputs where PCM up to 24bit/192kHz is supported.
That the CS1 is powered by 5V arriving at its rear-panel USB-C and thus provides some flexibility for those who like to roll their own (linear) power supplies. If that’s you, know that any audible benefits brought to bear by a linear power supply might be compromised by the presence/quality of any downstream switching regulators found inside the unit.
However, the real story here should not sail us by: that would be the absence of an accompanying smartphone app. The CS1’s network streaming support is entirely driven by third-party systems: Apple AirPlay 2, Spotify Connect, Tidal Connect, Roon and GoogleCast (which will likely handle the CS1’s network onboarding and configuration)
With no accompanying streaming/configuration app to develop or maintain, NAD could pass on any cost savings to the consumer. Perhaps this is one reason why the CS1 will sell for US$349, £299 or €399 when it begins shipping in March. And according to the press release, support for DLNA/UPnP streaming is expected to be in place by then — but BYO UPNP app.

Just a reminder: GoogleCast supports PCM up to 24bit/96KHz but does not offer gapless playback. Apple Airplay 2 does do gapless, tops out at 48kHz but, like Bluetooth, all streams will travel via the smartphone (or laptop) on their way to the CS1.
