Why ordinary power amplifier is not as good as digital power amplifier?

Very simple digital power amplifier generally uses switching power supply and analog power amplifier uses transformer. If you can take it apart and look inside, analog power amplifiers all use high-power transistors to output large radiators, while digital power amplifiers are small and have different weights! Digital power amplifier is lighter than analog power amplifier. The advantages of digital power amplifier are high efficiency, low heat dissipation requirement, simple peripheral circuit and low cost. Disadvantages: the sound distortion is great! The restoration degree of human voice is poor. The advantages of analog power amplifier are better sound than digital power amplifier, but the disadvantages are high cost, high heat dissipation requirement, heavy weight, complex circuit structure and difficult maintenance. I think you already know what his original amplifier was! And that's not a coil, it's a transformer. Haha! Then be popular! Digital power amplifier has low requirements for power supply and does not generate too much heat, so the radiator is also small. But the sound is not as good as the simulation. Although analog is superior to digital in sound, it needs high power supply and large radiator for low efficiency, but it has obvious advantages in sound. Add the above, no matter what you like pop or not, this is clear at a glance.
