One of my reason posting the same DAC again is because I not making any new DAC anymore. I listen the music from my digital source, with the SPDIF output, then it convert the data to the analog sound by using this Nakamichi Dragon DAC clone. I like it so much and this might be the most expensive DAC I've ever built. It sound so good, probably not the best, but I feel proud to having this DAC.
I guess more than three month has pass and I think I should revisit this DAC again.
Actually I have some issue with the sound, not really major for me, but I think it is lack of the detail music presentation. Probably because of the LPF cut-off should be setting up again. I also want to have cleaner digital supply to each PCM1704 DAC IC by adding the inductors, as per original Nakamichi Dragon DAC schematic.
So here are the updates.
