Here's mine in a Sescom box.. My own supply design, and all but the receiver board built by me. (Not for the smd challenged.)
Incidentally this dac sounds really good, better than my Zhaolu with minimal tweaking, and the fellows at TPA are very supportive. I recommend them and their products heartily.

Note I have no affiliation, just a very pleased customer.
I based it on a pair of COD with the considerably less expensive PCM1798 simply because I had the chips. I didn't have too many of the other parts and ordered them all from Digikey. The IVY I also built from a bare board, the output is unbalanced transformer coupled from the IVY balanced outputs. (I used UTC A-21 600 ohm transformers.) The receiver is their V.2 WM8804 based receiver.
A couple of comments, the dacs, receiver and probably the Metronome are static sensitive as are any cmos based device. Handle with care. I2S signaling is fragile, run it very directly to where it is going and be aware that the SCK signal can also interfere with the others. I stacked my receiver board and dacs in a single stack which eliminated some issues I had with SCK coupling into other things. The leads are just long enough to do the job and eventually I may replace the terminal blocks with samtec or similar single in line headers and mating connectors to further shorten the paths. (Depends on whether I add a metronome or other options.)
The power supplies are my own design, are total overkill, and take up about 3/4 of the available space in my sescom box..
