You don't know every batch of DX50 sold out. Merely iBasso used the cut off date of each batch before starting the next. The DX50 sounds OK, it's lack of soundstage and instrument separation is quite poor, not much better technically overall than an ipod classic. All you guys are getting is decent resolution and detail if you PUMP the amp section hard. Overall as an audiophile player, it's quite average. Even the little hisound Rocco BA sounds cleaner, and stronger technically. If DX50 was that good I would of put up with the bugs and drama and kept it. As a focus point check some of the sources I've owned on my profile.
