The reason for purchasing the HA-160D were:
1) audio quality
The audio quality is really excellent. Worth mentioning is the complete independence of the supplied power. With the Burson I have always good quality of sound. In my previous setup with a DacMagic I have opposite experiences. My compliments!
2) a DAC, pre processor in one device
What to say? A nice small box with sufficient resistance when connecting the headphone.
3) A better headphone amplifier
I used my NAD-3500 PE integrated amplifier as headphone amp before. Honestly speaking the difference with the Burson is not as striking as playing over my speakers.

Overall a very satisfied customer!
