Sound stage became much wider, more bass, more treble, speaker became less picky on position and angle. But during the diy, i found out that the pins hole on the pcb is wider than the v5 op amp. So i used 2 unit of 4 pin holder. And i need to bend the holder inwards in order to allow the op amp to slide in the holes. The position is off by around 1.5mm.
