New owner of dx200 here. serious great stuff. I own many desktop DAC, portable as well, like Algo db+ with Alo rx3b, mojo, nothing could match dx200.Strong point of dx200 is focus imaging, non fatigue detail, airy and not over sweet high. All freq spect render with texture, e.g. you could hear the detail in bass, mid bass, mid vocal and high in proper seperation (doesn't muddle each other even you turn up the vol). Some say bass is not deep enough, I say bass is accurately deep and transient is there, not boom boom boomy type which I hate. IF one think this is too thin, likely the headphone or iem you use is not your taste. I personally prefer dynamic driver IEM over BA, and recently I think hybrid is best. (e.g KZ ZS5) For full size I use HEK and HD600 moded.
I onw Chord dave, this dx200 really a run for my money compare to Dave and all the upstream transport ($$$$$)
By the way some have issue scan their SD card. I did not have a problem till I reset to factory setting one day, and after which I couldn't complete a scan which I could before. I took out the sd card and repair it under windows and there's error. My guess is during factory reset, write cache was not fully written to the card. Its better to eject your card in settings before you do factory reset.
oh also, some claim no sound benefit with custom cook rom. I use windowsX rom, it does upgrade the sound as mention above. Not to open another can of worm here, if you don't feel worth your time to try or even spend money on please don't, you will only get "thinner" sound.
