@RickSanchez I don't remember now however the XLR output has more often 2 times higher impedance than SE. So it would be too much for me considering low impedance hifi headphones like Aeons or Nighthawks/owls. Also I noticed the tendence that more and more new outcoming HPs have lower and lower impedance.
Btw. I have started to consider to buy only DAC like Toppind D70 or D90, I saw they have great measurments and reviews. I also have SMSL SP200 in home, however it is not internally balanced amp, so maybe I will buy something from Monoprice like 887 in the future (when it will be possible to buy in EU) and whole case will be solved for years.
