I don't know how other manufacturers' DAPs are behaving, but I have to say that I'm pretty impressed with iBasso's DX340. I've been using it regularly for a few months now, and the UI and software are
flawless [in terms of smoothness]. What I mean by this is no lag, no touch input problems, no freezes/crashes. It's running Android 13, and I'm pretty happy with it.
It has good battery life for what it is, imo. A pretty neat feature it has is that you can bypass the battery and run the whole DAP from your charger (in short, once the batteries are charged to 100%, the charger becomes the DAP's power supply and the battery stops charging).
It would be cool to see a place where consumers request features that they'd like to see in DAPs. System-wide [P]EQ would indeed be very nice. I'm wondering whether we aren't seeing Dolby Atmos because of the license costs or whether there's something legally preventing it from being utilized.
Anyways,
@Azalush, what you did with the DAP charts is one of the most valuable community contributions to the DAP space. Thank you for everything you've done, and I hope that one day there will be a DAP that will have what you are looking for. Personally, I'd love to hear more from you. If you share feedback, know that there are manufacturers that will listen to what you have to say and start working on implementing it.
