So I haven't been in here in a while, but I've got UAPP for outputting quality sound when I need it. Otherwise I use GoneMAD because I like it's UI and sound combo. What's Hiby? I check out the GooglePlay description, but of course feedback in here is going to tell me more. Why are you guys using it, what advantages does it have, and why not use UAPP?
On ad side note, does anyone else use GoneMAD here? I've been using it for a while and tested it against Neutron Player a while back. It's got a smooth UI and I like the sound, definitely the best compromise I've used as compared to UAPP for non-intensive listening.
