Where to place the clock for a DAC

Hi
I would like to try building a DAC using an R2R Ladder board, you can get them on Aliexpress and Audiophonics. the one I'm looking at has bck/lrck/data/gnd inputs.
My question is should the iancanada reclocker fifopi Q7 be connected to the output side or the DAC board side? I was thinking of having a transportpi mk2 on the output and a recieverpi pro 2 on the DAC board. But where should the clocks sit?
cheers
