When I first got this player through the mail I was amazed at the amount of power this device holds. Works great as a DAP or as a DAC with my mac since I have more of my music on there. The large storage was a huge plus for me since I have a large library. One of my favorite features though is that these players recently got the capability to stream Tidal from the device. With my Shure se846 I was further impressed when I paired it up with the player because the bass was significantly improved and when I play DSOTM in DSD I can really hear the difference from when I used to play it in FLAC. Overall, I think this player is one great device the battery life isn't as great as I'd like it to be when I play in higher resolution formats and after some time I have to stop listening when I feel the player is getting a bit warm. This player goes everywhere with me and I would highly recommend if you're willing to spend the money for the quality you're going to be getting with this DAP.
