I've had a NuPrime CDT-8 Pro for just over a year. Thus far, it has worked without any problems and the sound quality is probably the best I've had in digital. I'm using it with a Micromega MyDac connected via an Audioquest Coffee S/PDIF. It also has a sampling rate converter which allows you to tweak the sound. In my instance, the 88.2KHz seems to be best. You may want to read some reviews on it and see if it might be a good fit for you. Sound is very detailed and seems to reflect what is on the recording. In conjunction with everything else, I'm getting a deep/broad soundstage with excellent imaging. Even with a modestly priced DAC it performs very well.
