No, it’s not the best DAC in the world. It’s a fine DAC that was carefully designed to be a proper successor to the PS Audio Perfectwave DAC series. I don’t understand your intent with these questions. Of course I have a DS, I have multiple DSs, both engineering prototypes and three for my multichannel music system. I also have the prototypes for it which were built without regard for cost:

This system description is a little stale:
