I deepen the discussion to be clear.
Most powerful eq setting(hi-fi,hsa and wooduo)I don't like so much,I prefer a "dryer" signature so at the moment I opt for jazz eq
(I repeat user eq is useless for power and quality)and using iem,UE superfi 5 and sunrise xcape,there are no problems about
power,you can break your ears if you like it,but anyway little bit less than clip zip although a bit more wide and detailed.
Different story if you use a headphone.
I tryed with Audio-Technica ath-m50,Sennhaiser hd 380 and others with max volume
power is just enough,in hsa eq you have a small reserve.
I'm just saying I expected more from this player but maybe I just expect too much?
