Product Highlights:

1:) This power supply uses double-layer filtering to effectively remove high-frequency interference from other household appliances to provide a cleaner power supply. 2:) Precision discrete multi-tube parallel voltage stabilization method, ultra-stable operation, greatly improve the instability of the power supply, perfect removal of the original switching power supply, the sound is cold, hardened, unacceptable, and dynamic is not good enough. 3:) The large current supply can provide sufficient current, the background is cleaner, the high frequency is sweeter, the mid frequency is more transparent, and the low frequency is more powerful! 4:) After three years of testing, the various types of capacitors have been matched and compared to have a quieter power supply. 5:) The performance of the linear power supply is stable, and there is no interference such as high frequency ripple.
