my 2 cents
a few years back i tried a mojo (believe it was a mystique v3) and after extended listening i ended up returning it to ben... it is a very suave very smooth sounding dac, but in my system it I felt it lacked some drive, openness, and ultimate transient clarity provided by other nice dacs I was comparing it to (audio note 4.1, msb analog, chord tt2/scaler)... i suspect ben’s design objective and voicing target is to conservatively remove all traces of ’digititis’ from systems that may have those characteristics (either intrinsically or due to power or front end jitter/noise issues) and for those users, of which i think there are plenty out there the dacs are wonderful ... I have certainly learned that optimizing a digital feed can be quite a pain
all this said, the mojos are nice super smooth dacs but to me the challenge for higher end users is to make sure the front end feed is optimized before selecting any ’keeper’ dac
