Yep, Poweramp is a good player and I’ve tried most of them. At .99 US there’s not much difference from “free” and there’s a lot of functionality and customization possible with it. Seems to work well with various headset controls and that hasn’t been case with other players I’ve tried. If you’re averse to Play Store purchases there is a way to buy it direct through their website or at least there used to be.
Another option is to sign up for Google Opinion Rewards and start raking in that sweet sweet survey money.
Yea it has so many features but i am using external DAC so the sound quality is good no matter what player i use.
