My Batch 3 DX100's battery was getting worn out, the battery indicator was broken, and this weekend the charger connection stopped working. I reported the problem and shortly thereafter, got authorization to send it in for maintenance. I dropped it off at FedEx Tuesday night, earlier today it cleared through customs, and I just got notification that it was delivered to IBasso. $90 to ship, not that bad for two-day service to China.
Anyway, they're going to hopefully fix everything, and install a new battery--just a $15 charge for the battery. I'm using my backup Sansa Fuze with Rockbox for the time-being--not all that bad with noise-cancelling headphones, but using the headphone jack of the Fuze for home and car use after the having the DX100 for a year is a bit painful. Hopefully I'll get my renovated DX100 back next week.
One thing I did realize though after temporarily going back to the Rockboxed Fuze, is that it would be nice if IBasso could go add more functional features that Rockbox has. For example, go beyond gapless (which is still glitchy for me--I still hear a brief pop in the beginning of the next song), and add some cross-fading features that Rockbox has. The gapless on IBasso cuts off some of the end of the outgoing song and the beginning of the incoming song, instead of mixing like Rockbox. Maybe the V2 framework will have this, or whatever firmware comes with the DX50.
Also I do miss Rockbox's speed. Swapping micro SD cards on the Sansa Fuze takes seconds, and there's almost no latency--like 2 seconds, when adding or deleting songs to the card. With IBasso, that can sometimes take over an hour. Like a lot of you, I put up with the delay because the sound is so incredible, but 64 GB is not a lot of space for 24 bit music--it would be awesome if these high-end players wouldn't take forever to index or whatever the hell they do for an hour after changing content.
