How good is the DAC on this phone with custom roms and V4A

I plan to get this phone refurbished from ebay deals section, how good's the DAC for listening to Music with the lastest official 6.0.1 roms on the verizon one and how good the DAC sound when you use V4A on a custom roms ? I personally listen to chiptune with XMP Mod Player with AudioTechnica ATH-M50X. I am coming from an HP Touchpad with Pac-Rom running V4A on it. Would you say the DAC's decent compared to modern phone like the new HTC 10 or Oneplus 3 ? Thank you.
