I don't even have DVC turned on since I am not using any EQ and it still seems to sound better. With DVC on, in my case with no EQ being used, seemed to just make the volume lower.
Poweramp has a feature called dvc which brings out the sound more by leveling frequency volumes. If its off and you have bass boost, whenever bass plays, all other frequencies quieten, which i dislike. Dvc levels out the slightly muted frequencies and then everything sounds great
