IHIFI812V2 top portable music player (built-in WM8740 decoder, AD8397 amp)to create the mostserene background, clear, sweet, wide sound field the sound!

Portable audio player line system, while not complex, but the difficulty is to do, such as the signal to noise ratio improved from 70db to 90db, probably as long as one day, but from 90db to 95db upgrade may take 3 months. Each capacitor model, each resistor, and even the direction of each signal line, we have done a lot of experiments, only pcb design proofing has reached more than 10 versions. Even at the cost of raw material, widely used in the industry's top components.
