after 5 years still enjoying usb audio player pro for long critical sessions and listen with bt when working out- drawing-daily walks with poweramp on my lg v20 with beyerdynamic dt 770 250ohms i dont plan on updating for a while at least for the next few years. Really enjoying my SIMPLE SETUP. In the end it always has been about the music and both of these apps do it beautifully. But i do love and enjoy seeing other peepz setups and audio rigs as well. now go and enjoy your music the WAY you want. blessings
