You're not really comparing apples to apples, since XDP-30R is a DAP and the Dragonfly Black and the Mojo are DAC/headphone amp combos. The advantage with the XDP-30R is that you get the "source" included in the package (no extra addon bits..) and also the advantage of balanced headphone operation, which from the discussion here seems to make a dramatic difference in sound quality.
The Dragonfly Black, despite using a different (and single) version of an ESS DAC, is probably very similar to the XDP-30R due to the ESS house sound.
Yes I know the dap vs the dac issue, and I have to admit that it´s really convenient to only have one source instead of a phone, cables and a dac/amp. But the reason why I compared it to my dragonfly is because the XDP 30r is four times the price in my country, and in my opinion you should be paying for some difference in sq as well (due to the difference in price). What do you guys think?
After listening some more with the XDP 30r, I belive it´s a bit more open and spacious compared to the Dragonfly Black, while the black has a bit more details in the mids and lows. Again, just my opinion. I will try to listen to it as much as I can for the next week as well and see if the sq and the wifi connection some how improves.
I just have a question regarding the balanced output: what kind of cables are you guys using to play from the balanced output? I use a small cable from 3.5mm to 2.5mm that i plug into my original cable from my headphone (which is 3.5mm), but I think that a lot of details disappear when I use this output compared to the 3.5mm output. However, the balanced is more open and spacious than 3.5mm.
