I'm looking for a replacement for my trusted and beloved Cowon J3 for travelling. I do own a FiiO X5II, but I don't really find much of an audible difference when riding in a train/plane. It does, however, fail to last a single day, which is a real buzzkill for me! What am I looking for: - A player with super long (50+ hours on mp3 tracks) battery life (need not be super light, because carrying my X5II with powerbank is close to 500g.) - 24bit Flac capability (I don't hear a difference, but I don't want to convert my files to 16bit either) I don't need fancy eqs, balanced output, huge touch screen, got no need for amp cards, dsd support, 1TB internal memory, or sabre flagship DAC chips... ...phones used: I use the iBasso IT01 IEM and my Beyerdynamic DT1350 (replaced my HD25-1/II a few years ago) when travelling. Afaik, there's not much need for super strong amping, since the J3 doesn't go beyond 20 - 25 (volume) with the iBasso, or ~30 - 35 with the DT1350. So far, my current favorite would be a Plenue D, but Im open for other recommendations.
