For those that were curious about this I received one of these boxes last week and had a little time to work with it tonight on the bench.

The chips are absolutely DAC chips. The three signal traces I mentioned earlier are the three clocks and the separate traces that go to one DAC each looks to be serial data. The pinout of the DACs is:

Pin 1 = Serial Data
Pin 2 = Bit Clock
Pin 3 = L/R Clock
Pin 4 = Master Clock

The master clock runs at 256xFs for both 48kHz and 96kHz playback and the DACs do receive data at 96kHz when playing a 6 channel LPCM track at 96kHz into the box over HDMI.

Going along with this I also received the 4x SPDIF output card PCBs. I am going to test that in the CLUX box to see if I can kill two birds with one stone.

I *might* be able to fit this card inside the CLUX chassis. If I can I think I will wire it to the existing outputs within the box as I don't think I can fit RCAs in it.
