Pros: Excellent sound quality, flexible w/ different amp cards
Cons: UI a bit awkward, battery life a bit too short especially with balanced amp card, a bit warm after playing for half an hour and longer
Can't believe there is no review for this excellent DAP yet.
I won't duplicate what I said here:
No regret after I bought it the second time, and this time I'm gonna hold it until a better Hifiman DAP comes out. Would have given it a full 5 stars if not due to its UI.
