Device model - Onkyo DP-X1 - Digital Audio Player ROM version - Android version 5.1.1 stock ROM 2x ESS Sabre ES9018K2M and 2x ESS Sabre 9601K in BTL config and Active Control Ground (an industry first) I use Poweramp alpha build 703 now, it works well. I post this specification just in case for dual dac and full balanced android player.
I use Poweramp build 703 with my Onkyo DP-X1 (DAP) android version 5.1.1. It works well. It also works with DSD files though.
