From what I read on this document, it seems like a audio processing module that does more than just DAC.
It also can do signal processing (equalizer and stuff) , the DAC part and even a direct analog output for headphones:rolleyes:
But it's main job seems to be digital audio processing, cowon could have implemented the amplification part elsewhere in the circuit. IDK
Looks like the D indeed uses a wolfson, glad I placed the order and regret not paying 10 bucks more for express courier delivery
The pcb tracks from the wm chip go directly to the hphone jack. I may open again and see if I can trace to anywhere else. I must say the build quality is good - a very 'solid' construction.
