Good Audio MOD to enhance SQ?


Hi there, is there any good audio mod to enhance SQ on MIUI v5 for MI2S?


I use Volume+ from the playstore. That is the only one i felt good enough and can make speaker louder. Have tried other mods like Beats, Viper etc but they bring lot of distortion. Hope this helps.
 
Viper Fx and XHifi excellent with proper settings and selecting correct convolver
