Just wondering if there is any good design of the pcm1794 out there, besides the COD from TPA? I am looking for something with i2s input, low noise regulators, preferably dual mono pcm1794 and pads for external balanced IV stage. I vaguely remember a site from Japan with some nices designs but I have a memory like a sieve, so would appreciate if someone reminds me of that site. 
Cheers.
