I have this DAC, year and a half IIRC, awesome out of the park design by John Westlake, from what I read it seems Project is not using John anymore (what a shame) if you look inside the DAC you will see perfect geometry design separating specific components etc. there was even a new firmware taking the DAC to new heights that John announced at pinkfishmedia but he went silent, I guess probably because legal agreements with Project
I use the DAC with separate power and it is really amazing sound for the money, I know some other DACs are cheaper and measure better and don't doubt they are as good.
Thanks Amir for the review, just confirms my former opinion on this DAC, I admire John's work too.
