Poweramp setting
1. Equalizer flat or extra vocal increases the frequency of 1KHz by 2.5dB
2. Increase the preamp by 5.6dB
3. Tone : Bass 60% and Trebel 42%
4. increase stereo expansion by 4%
5. volume control of 20% -30% do not over it, 25% of my recommendations
6. increase the Replay GAIN by 11dB
7. activate Hi-res mode if your device supports (Settings / Audio / Output)
to add sound quality can combine Poweramp and Re Equalizer.

3. FX : Surround 4, Reverb, Deep Bass 6
