Conclusions
We are spoiled at ASR with discovery of good number of high-performing dacs and headphone amplifiers. Given the cost of Yulong D10, I expected it to match or beat those reference devices. That did not happen. A persistent high noise floor (measured, but likely not audible) persisted throughout the measurements. Power output with 1/4 inch jack at 300 ohm was also a bit disappointing.
On the positive front, if you use balanced output, you should be able to drive any headphone to very high levels of fidelity. Most of our reference level DACs lack headphone amplifiers and that is integrated here in the D10. In addition, it is good to see regulatory certifications on the D10.
Overall, the Yulong D10 leaves me just a bit cold so I can't fully recommend it. It is up to you to decide if its feature set, availability, etc. makes it better than other recommended products.
