E1DA was founded by a family of a Russian engineer “Ivan” who is living in China for the past 14 years. He is a freelance designer in SMPS/Class D/DSP/Embedded departments. His older son is a coder for Android and iOS devices. “Ivan” started the brand after he purchased a full-sized planar headphone but couldn’t find a good enough USB DAC/AMP to power it well within his price range. Today, E1DA’s Portable PowerDAC series has got universal recognization for its ultimate driving power and clean output performance. The engineering by the E1DA family is top-notch, and so are their products. Check out their outstanding PowerDAC V2.1, 9038D, and more products available for you with HiFiGo.
