The player sounds great, its the poor UI that is frustrating. I really love iBasso as a company. Im just disappointed that after spending so much money I am not experiencing a premium device. Im sure they will sort it out with SW updates although looking at how many dx200 fw there are compared to dx150 Im not sure how long this will take? :/ I owned the DX120 but TBH I thought the sound was a bit of a mess, quite incoherent. People over all seem to like it though I installed Neutron player on the DX150 and have to say Im very impressed so far. The UI is much more reasonable now - you can actually scroll with some degree of accuracy consistency!
