compared RedWine moded AK100 unamped to iBasso DX50 amped with T1. IEMs used 1p2.
i like DX50 amped a lot but comparison shows RWAK100 outclasses DX50 even when DX50 amped. RWAK feels more refined, spacious, more black velvet space, easier flowing and more black space between notes. DX50 holds a lot good for itself and is far cheaper DAP but talking in pure music terms i would give good edge to RWAK. each DAP is a joy to hear but RWAK is still the best portable solution while DX50 will sound its best amped but can feel a bit edgy and sharp unamped.
music listened in testing side by side:
and more Clannad works (could not find Chillout version i have at home on youtube but these compilation are enough)
