Nothing like being in the market for a DAP these days.... awesome. I owned the x7 mk2, WM1A, QP1R, obviously the QA361, AUNE m2S, and a bunch of others. Also owned all of them at once (except 361) so I compared them all pretty extensively, trying to settle on my favourite. These are all really great sounding players, some with far better UI and also some with far more features. You can decide what you need in that respect so I'll just quickly let you know what my - Personal - preferences were regarding sound quality/signature. I really liked the x7 mk2 with its super detailed yet still musical (too a degree) sound sig. The QP1R actually sounded quite similar but had audibly less jitter, blacker background, smoother presentation yet with all the details The Sony was a beautiful player which sounded more analog to me (kind of like my old Master 7 PCM1704UK x 8 DAC) but did not present the details as well as the QP1R imo. It was a pleasant sound presentation but definitely different to the others & I preferred the more crisp sig of the QP1R. I also found the EQ'ing did not affect the sound quality in a positive way imo. The AUNE m2S is a super basic player (just like 361) built just for SQ. Its sounds fantastic, musical yet clean and hard to fault but its a little old now that so many new awesome DAPs are coming out so you might be happier with a newer offering. Also my main iem was the ie800. I personally settled on the QP1R which was the most refined sig imo. I sold the others except the M2's. The QP1R & ie800 got stollen so I went on another quest for a TOTL DAP. I settled on the QA361. Unfortunately I have only had it for a couple of weeks and I don't have my ie800 to compare with but it is a very impressive DAP. With out the direct comparison I would still be confident in saying it is at least as impressive as the QP1R. I hope that helps a little mate.
