The device features an advanced integrated feedback design and proprietary high-speed gate driver error correction (PurePath Ultra HD). This technology enables the device to maintain ultra-low distortion across the entire audio frequency band while delivering flawless sound quality. Using the original TPA3255D2 power amplifier chip. The main filter electrolytic capacitor adopts imported capacity of 1000UF/50V*4 to ensure strong and continuous power support. The resistors use high-precision chip resistors to ensure a good signal-to-noise ratio of the whole machine. The use of audio-specific inductors ensures that the sound is crisp and powerful. The PCB adopts 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and full tin spraying process to ensure good passing performance of large and small currents.
