(1) the “standard” internal phone DAC is a cheap comparative low level part and low-level audio performer available to be bypassed with an external mini- mini-DAC/headphone amp capable of hi-Rez digital file playback
(2) the “standard” internal phone player app is likewise a low level minimal quality and comparatively poor performer lacking hi-Rez output, that can be supported,anted with a new player app capable of hi-Rez playback.
- The external USB MINI- DAC (and Apple camera Lightening to USB converter if required for IOS)
