18-bit : CS8412 + DF1700 + PCM58PK ( postscript or PDF )
20-bit : CS8412 + DF1700 + PCM63PK ( postscript or PDF )
20-bit : CS8412 + DF1700 + PCM63PK + Jitter Reduction ( postscript or PDF )
power supply : Power supply for 20-bit DAC ( postscript or PDF )
20-bit : AES20 + SM5803 + DAC20400 from The Parts Connection. (WITHOUT analog filter!) ( postscript or PDF )
PS. I am not shure this schematic will work!
I am sorry that I didn't write any articles or instructions for these DACs. However, there are several useful documents at http://www.seraf.uio.no/doc/lyd/DAC/ . I wish those documents can give you some helps. The next design will be AES20/21 or CS8414 + SM5842 or DF1704 + PCM1702PK or PCM1704. Hopefully, I will write article for the new design.
I strongly suggest everybody upgrade to CS8414. Even though the CS8414 and CS8412 are almost identical except the CS8414 has the ability to handle 96kHz signal. However, after I replaced my CS8412, I noticed that CS8414 has better audio performance. It provides better bass, better resolution, and deeper sound stage. Try it! You will like it!

NPC Digital filters: SM5813(DF1700) , SM5842. You can also find them at http://www.npc.co.jp .
Most of the parts should be avaliable at digikey. Some of the parts can be found at The parts connection. or at Audio Crafters Guild .
PS. I don't sell any parts of the DAC!!
