He has been a great resource for me. I now have a Musiland Monitor 01 USD 2012 that I have stripped down to just the board that I will be using in my DAC. Good reviews, improved performance so far over my stock USB.
I can confirm it's working all right.I'm now using it with PCM1793,it outputs up to 24/192 with no problems.
