I am not turst the sound quality is better than traditional amp, but gettting the parameter and fit into the module, the sound is natural, may be it did not need A/D D/A from CDP.
One major factor is, you need to measure your speaker performance and write the parameter inside the amp. Otherwise, it is a normal Digital Input Class D.
My next progress is seperate the IIS input, making a digital crossover inside the IC (total need 2 pcs of IC), and output HF, LF seperate of 2 channel. |
