The most important thing to choose a power amplifier is "good voice, good power". "Good power is easy to find, good voice is hard to find" is a pet phrase of enthusiasts. If we increase the power, we will have better power. Some domestic power amplifiers are very powerful.
I've seen a domestic power amplifier with several thousand yuan. It's very exciting to push the floor box. It's more complicated to make a good voice. If you want to have a noble voice, you don't have to rely on strength alone. It's going to cost more. Choose from the sound effects. This is the key, focusing on "listening". The specific listening method is to listen to the current sound first. At this time, unplug the audio input line and adjust the volume to the maximum. The human ear should be about 20 cm away from the speaker, and the noise should not be heard, or the noise is very weak. Then play the music you are very familiar with. Listen to the stereo carefully. The bass should be deep but not muddy, the treble should be bright but not sharp, and the midrange should be mellow. At this time, the volume should not be too high. High volume does not mean good sound quality. Do not be misled by unscrupulous businessmen.
