The digital power amplifier uses two TPA3116D2 chips as the core output, with a power of 100WX2, which is enough to drive 3-10-inch home speakers. The distortion is very low. The excellent circuit design and material matching are very sophisticated and particular, so the sound quality is pure, low-frequency and full, and the noise is very low. Paired with a negative feedback tone preamp composed of the certified 5532 king of op amps, the high and low frequencies can be easily controlled and the sound effect is excellent.
