tpa3116 has better sound quality.
The tpa3116 is a Class d power amplifier from Texas Instruments' tpa31xx series. It has the characteristics of wide voltage input range, high efficiency and no filter. Its efficiency can reach more than 92%, so you can use PCB heat dissipation without an external radiator. The actual design has used this series of power amplifier, and it does not need heat sink, and it can work stably. The official data shows that there is no need for an external filter, and we usually add a filter for practical applications.
