There is no doubt that DTR1+ has become my favorite DAP. The sound is so emotional, detailed and powerful.
With it, all my earplugs have become so charming. Compared to popular Android players, I personally prefer its simple and responsive operating system.

Don’t know nuthin’

….bout soundstage, u shape vs v shape, timbre or balanced armature. But my ears know good sound and they tell me that this “sounds” as good as my L&P’s, my Lotoo Paw Gold and my A&K’s which cost at least double what this unit costs. Paired with Dunu, UM, or Shure premium items and it’s musical heaven for pop, jazz, classical or ambient . Now if my case would arrive pronto as this little baby is getting all scratched from overuse.
