If it matters I have the A10 and also a C2700 and if i was honest the C2700's Dac2 is as good if not more detailed then the A10's internal DAC. I'm not sure if the newer ones are better but I find the A10 to be rather boring using the internal DAC. I'd suggest looking at the ones that do not have a DAC and save your self the money. you can always upgrade your DAC later.
If i was really honest I'd say the A10 as a streamer is ok but not any better then my prior optimized PC based streamer, but defiantly better then the Roon Nucleus I had as well.
