Unlock True HiFi Sound: An upgrade for your WiiM Pro. The linear power supply reduces ripple noise as low as <30μV, eliminating harsh high-frequency noise for a pitch-black background, wider dynamic range, and crystal-clear audio details. Audiophile-Grade Components: Powered by a UK Talema toroidal transformer, EMI AC filtering, and a CLC matrix filter. This high-efficiency design blocks grid interference and electromagnetic leaks, delivering pure, stable power to your DAC.
