Physical Unit (Part II - Side)
There are three buttons on the left side of the unit. The printed labels are on the bottom of the DAC (so the top is nice and clean). Not a great choice font wise as the letters I and L in the word filter make it look like a typo.
The Display button turns the small OLED status on or off. When the status is off, a tiny recessed notification LED (blue) near the headphone output will lit up (letting you know the DAC is still in operation).
Not entirely sure what the SRC does as toggling that don’t appear to change anything on the status display, and as far as I can tell, no audible change.
Filter is the low pass filter (LPF) to apply. Different filters are used for PCM and DSD. So far in my short listening session I prefer PCM4 and DSD2. This of course is my subjective preference so YMMV.
Really don’t like the positions of these buttons. Every time I moved the DAC on my desk, inevitably I will push on one of the buttons. Happened to me so many times it’s getting annoying and I wished xDuoo used buttons that’d only actuate with more force.

hey, u still have this thing?
i think what happen is that the opamp chip needs change. Consider LME49720 if u dont fancy to do any soldering, or just buy the Burson V5i if u have budget, easier.
I crossed this text when i roll the opamp, and i think my opa1612 is bad, and got this text.

Yeah still have it. Using it mainly for work. Am considering a Burson V5i, will eventually buy one (waiting for a sitewide e-bay discount to pull the trigger).
