I have had my eyes on the Burson DA-160 and the W4S DAC1. At the moment I do not have a need for balanced outputs and asynch USB implementation is not a priority. I have read reviews on the Burson HA-160D and saw that most preferred the W4S DAC2 (I understand the DAC1 and 2 sound very similar) for it's greater detail, but I haven't been able to find many comparisons with the DA-160. Has anyone has any experience with them? The associated gear would be a Pass Labs B1, Rotel RMB1075, and LSi9s.
