Offered here is a brand new NAD D 1050 DAC. I bought it a few months ago but never had a chance to use it. I took it out of the box the first time for pictures. The distortion on the front of the DAC is from the protective film that is still on the unit. Their literature lists the following details:
The NAD D 1050 USB DAC is the best way to add Computer Audio and HD Digital to your component hi-fi system. Both the digital and the analog circuits are highly optimized and based on techniques developed over 40 years of NAD audio engineering excellence. The digital inputs cater to many different digital sources. SPDIF inputs support balanced AES/EBU coaxial and optical connectors. The USB input is very special; its asynchronous operation mode uses the D 1050s 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 192kHz signal transmission.
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 88.2kHz and above.
NAD packs a lot of premium high spec parts inside the D 1050. But premium parts need optimal implementation to get the actual performance they promise. This is where NAD 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 soldered with lead-free high silver content solder. These details all contribute to the remarkable performance of this advanced DAC.
Analog outputs are fixed and include both balanced and single-ended connections. Also included is a premium quality headphone amplifier output that includes a high quality volume control. Output impedance is extremely low minimizing the effect of connecting cables and keeping noise vanishingly low.
