Esoteric K01 XD and Luxman D10X are the 2 top players now with built in DAC very hard to get either one . I started out with K01 XD very good , I’m now comparing it to the Luxman . I didn’t have a chance to listen long but will tonight . I feel so far that there is a good chance the Luxman might come out on top . Sent from my iPhone using Tapatalk
