I had the DX50 for about a week now and compared it back and forth with the Fiio X5. And i guess the X5 is going back to Amazon so i get my Money back. I don't really have a need for 2 Players.
Even though the X5 did cost me 100€ more, i always come back to listening with the Ibasso DX50. On Paper, the X5 is clearly the better Player. The buildquality is awesome, i love the display and the option to have 2 sdcards in it. But as much as i should love the X5, the DX50 just grew on me that much faster. I really like the Touchscreen (although i dont like the quality of the display) and the navigation is better compared to the Wheel of the X5 (one thing i hate about the X5).
In terms of sound, the DX50 in my opinion is more neutral. I did some extensive A/B listening with the X5 and the DX50 and the X5 to my ears sounds brighter (especially on Drums) and fatigues my ears much quicker. I really can't pin down, why the DX50 sounds better to my ears, but i guess i will send the X5 back. An DX50 with the chunky buildquality and the 2 sdslots of the X5 would be all i need.
