I just got my micro iDSD from a local dealer in Beijing, China! Here are some pics :)                                  

Me. Can't wait, please!

  It's TI website that got distortion figures back to front. PCM1792 has .0004% and DSD1793 has .001%, according to the datasheet. 

  My mistake, sorry.   But I still don't believe DSD can handle both formats natively. The datasheet shows there is still a up-sampling module involved.   http://www.ti.com/lit/ds/symlink/dsd1793.pdf

  What do you mean by natively? All the DACs I mentioned are advanced segment DAC with DSD/PCM interface. There is no difference between DSD1793 (PCM1793) and PCM1792 in their functional block diagrams, except the latter have better dynamic range (113dB vs 132dB), lower THD+N (0.001% vs...

  As for the "better specs", I mean those chips have better SNR, dynamic range, THD+N, etc.    If some chips are widely used by high-end devices, I think they are proven to have decent sound. I might be wrong.

Hi ifi,   Thank you for sharing info of the micro iDSD! I own a nano iDSD and I am very satisfied with it. My question is, according to the PCB photo, the micro iDSD utilizes two BB DSD1793 DACs (in dual mono mode), the same as the nano iDSD, why don't you use a higher end model, such...
