Review on Pro-Ject DAC Box DS (Silver): High-performance Digital to Analog Converter for Crystal-clear Audio Conversion by Brandon Woodson

I can only speak for what I received. It was opened, which happens, but inside there were open packages and wires that were not twisted on the wires. It was annoying. I tried it anyway and the audio was good with a noticeable difference between filter 1 and filter 2. The advert says it supports DSD but I couldn't find anything to suggest so and it was returned. The instructions are useless in this regard. Some things I tried (I returned it the day after receiving it, I found that the soundstage wasn't very good, but if I had kept it this could change with 100 hours of recording.
