There is a review by Dagogo: http://www.dagogo.com/HarmonixDAP-777Borden.html which I think you will find interesting to read, and it pretty much answers your question.
I own a new Reimyo DAC and like it, but I have no experience with the old version, so I could not give you any personal comparison.
