I have been sitting on the fence for quite some time, listening to people either falling in love with their DX50 or going insane about the quirks and bugs that the DX50 is "still" struggling with and going full crazy with their posts here.
And, it's really amusing!!
My 3rd batch DX50, for one, has not faced any major issues.
I do agree, that in the beginning I was very frustrated with the special characters in tags and stuff, etc...But, I cleaned up all my tags patiently, and the DX50 then worked flawlessly.
It's the sound quality that has been keeping me from replacing it or selling it off. Not to forget, the intuitive touch screen interface and more than enough connectivity and storage options.
As for using the DX50 while carrying it in the pocket: I have twice gone running with my DX50 and TF10s, and nothing seems to bother it while playing music. I also tried carrying it in my shorts' pocket- no issue whatsoever. But then, my unit might not have been subjected to exactly those conditions, that others are talking about...
I can easily say that I love my DX50 and am pretty happy that I ordered one. For $240, it cannot get any better IMO - awesome SQ, excellent UI, great ergonomics.
But, that being said, I'm eagerly anticipating the Fiio X5, which just might beat the DX50 in all aspects...!! I had a chance to try my friend's X3 for a day or two, and I must say that it was pretty stable. Athough the SQ was nowhere near DX50, hence, did not order one.
Lastly, I want to say that : it really is infuriating that the DX50 is still marred with a lot of bugs after several updates, that keep popping up from time to time. If that is not enough, an update does not necessarily mean that all that was seemingly bug-free will remain so... For instance, I had no issues with .cue and ,m3u files in the folders in V1.1.6. But, the day that I updated to V1.2.2, issues started cropping up with DX50 playing snippets of songs before skipping on to the next track.
Anyway, I have high hopes for the DX50, since it's quite nearly there "For Me", where I could stop worrying about my DAP and start enjoying music without any kind of issues bothering me.
