After I switched last year with the stationary music system fully HIGHRESAUDIO or lossless compression of CD, I was very excited about this mobile player. After 2 days of test I want to share the following experiences: The sound with the corresponding headset is awesome, as when connected via digital and analog interface to audio system. The sound is transparent, with high resolution, the individual instruments come out well. Only the current availability of the memory card size always allows only a subset of the players with larger music collection in flac. The 128GB there now, perhaps soon follows a 256 or 512 GB, would be nice. The service is okay, awesome would still back 2 more keys, Enter and level, then one would have to rarer the menu. In sum for this price highly recommended.
