Hi darkfury,

I haven't completed my connection yet, I have a circuit board half finished to combine my DAC receiver IC plus an analogue switch IC so that I can choose I2C or SP/DIF inputs. I'll post photos once completed.
Regarding your query, you will need to break into the circuit board traces between your receiver and converter IC's, something like the drawing below.

Hope this helps!

Audi0,
Do I need to desolder CS8412 receiver chip
before connecting the 4*1543's to I2S out?

Hi darkfury,
I think it would be advisable yes, but I would be more inclined to cut the tracks rather than remove the whole receiver chip. That way you can easily re-connect if you need to with a bit of solder.
I am adding a switch to mine to select either I2S or SP/DIF inputs, I'll be etching a board soon.
