headstage arrow is the best amp i tried and I use it with cowon d and ak380
without headstage arrow music would be boring coming out of daps alone
Agreed. Way more energy and heft to vocals for me. Bass makes the most difference on high energy tracks. I presume people have weak amps or low Ohm IEM's and or listen at low levels will be the one's that say an amp is not needed and that would be true. Anything else would not be true. It's hard to tell the difference but there is a slight difference. Plus I like an amp as I can quickly adjust the volume for different track recordings as I don't like to modify the music to normalize the volume like others do.
