Requests for Hi-Res Support (please state which build of Poweramp you are using) in Poweramp Feature Requests Posted May 11, 2016 On 12/4/2016 at 8:08 PM, maxmp said: Usable bit width is hard to measure independently - it can measured vis SNR, but there are to many factors which affect SNR (most DACs are 24/32 bits nowadays, but there is a noise in lower bits anyway for most audio content), but sample rate is easy to detect. Axon mini is marketed to have the almost the same DAC/audio 32bit chip as Pro. Axon mini produces max 48khz. I will try to obtain Pro model for tests, but that will certainly take some time (as they are available in selected parts of world). ZTE Axon Elite (A2016) on Android 5.0.1 and you can select Wired Headset/AUX on Hi-Res output. It says Snapdragon 24bit PCM, so I don't know if it is using the hifi chip or it has something to do with the CPU.
