I really love to use Poweramp. I think Poweramp is too difficult to set many options for first using people. Than, I think that options have that's short explanation is good to use for user. Like, at EQ setting, reinforce the 31Hz will be heard bass more bigger, 4K or 8K will be heard vocal more, at Reverb, feature of each settings. Ah, last, my small hope is that improve the Poweramp's lyrics interface. Sometimes it is unconvenient. I'm korean so that my sentence is looked like strange, sorry Thanks to read!
