Thanks, guys. Will keep searching for user reviews.
@edincleve,
One thing I can tell you regarding the Chord DAC's is that they use wall-wart power supplies, whereas the Bifrost Multibit has an internal PSU and you can use your own power cord.
I owned a Chord QuteHD DAC and although it was extremely smooth, it lacked bass due to the switched-mode power supply (SMPS) in the wall-wart, rather than a using a linear PSU. Now, the Bifrost is probably using a switched-mode chip as well, but it is a better design in terms of power supply since there are separate supplies for digital and analog sections.
