Does power amp improve sound?

It’s possible for two amps with slightly different wattage ratings to sound different, but all things being equal, they won’t produce a different volume. … A better amp will make your speakers play louder and sound better, but it won’t make bad speakers sound like good speakers.

Note:
please make sure the power supply is not more than 5.5V and
please don’t do reverse polarity for “+” and “-“, or else, it will burn the board.
