"Big, Meaty, and Fitfully Bouncy"
NAD's D 1050 USB DAC is an ideal way to add computer audio and HD Digital to your component hi-fi system. In fact, all digital sources will get a boost when the D 1050 takes over for the inferior digital circuitry found in everything from Blu-ray, DVD and CD players, to music streamers and set-top boxes. Both the digital and the analog circuits of the D 1050 USB DAC are highly optimized and based on techniques developed over 40 years of NAD audio engineering excellence. There is no reason to sacrifice audio quality for convenience, as the D 1050 vividly demonstrates.
"I warmed to the NAD D 1050 from the get go and one of the first aspects of its performance to stand out, in a good way mind you, was its bass response which is big, meaty, and fitfully bouncy while retaining a nice sense of tone," raves Michael Lavorgna in his AudioStream.com review for August 7, 2013.
The D 1050’s digital inputs allow you to connect many different digital sources. SPDIF inputs support both coaxial and optical connectors. The USB input is very special. Its asynchronous operation mode uses the D 1050’s high precision clock to control the output of the connected USB device for lowest possible jitter. It also supports USB Audio Codec 2.0, allowing 192 kHz signal transmission via USB.
Making it Count
NAD packed a lot of premium high spec parts inside the D 1050 USB DAC. But premium parts need optimal implementation to get the actual performance they promise. This is where NAD’s expertise with both digital and analog circuits shows its true value. Ultra short impedance-controlled signal paths are made possible by multi-layer circuit boards and micro-miniaturized surface mount components which are soldered with lead-free high silver content solder. NAD also found that it could further reduce noise by isolating the power supply from the sensitive analog circuitry by using a highly efficient external type. These details all contribute to the remarkable performance of this advanced DAC.
Magic from a DAC
The digital processing of the D 1050 features Delta/Sigma architecture with active oversampling filters. This technique effectively reduces out of band noise while maintaining linear phase response and virtual elimination of filter ringing in the pass band. This assures detailed and extended high frequency response while taking full advantage of the extended response of recordings sampled at 88.2 kHz, 96 kHz, 172.4 kHz and 192 kHz. Separate precision clocks fed from pristine DC supplies keep jitter (digital timing errors) to an absolute minimum. Everything is bit perfect. NAD does not upscale or downscale sample rates, and the incoming sample rate is indicated on the front panel display.
Balanced and Unbalanced Analog Outputs
Analog outputs are fixed for highest resolution and include both balanced and single-ended connections. The D 1050 also includes a premium discrete headphone amplifier output with a high quality volume control. Output impedance is extremely low, minimizing the effect of connecting cables and keeping noise vanishingly low.
GREEN, GREEN, GREEN!
In designing the D 1050, the NAD team focused on finding new technologies that can improve musical performance while requiring less power to operate and fewer non-renewable resources to manufacture. The D1050 is a DAC you’ll be proud to own.

"I like being surprised and the NAD D 1050 surprised me in so far as how much pure listening enjoyment it offers. With a host of digital inputs including an asynchronous 24/192-capable USB port, a very nice sounding headphone amp, and single-ended and balanced outputs, the D 1050 wraps up a lot of functions into a visually and tactilely appealing package that also happens to be damn fun to listen to."
