Very confusing post. If everything is incredible, why worry about the power supply? Did you mean that the sound was lacking, not incredible, and you were interested in improving the sound?
Since it seems to be considered to be a good value, I’m guessing that the power supply is of a modern design and a much better low noise switching supply than you find on lesser devices. If this is true, you might need a more expensive linear power supply to hear an improvent. All LPS are not created equally.
