have you a link so i get the context?

should function at least
At head-fi. They want to take i2s from a Singxer F1 usb to i2s/spdif converter and use a wm8804 to convert... Seems plausible

yea not sure them guys are used to soldering much,
11/10 for enthusiasm though
their signal path looks really long :(

id guess the newer xmos chips should be better than f1
someone stated the diyinhk dixo pro was better for him there too
i guess under the hood it's the same as the new green 384khz 216 chip board at diyinhk

i see here spdif can be reclocked by a 74 flip flop

so id be trying that first

its kinda simpler when everythings i2s
modding the f1 might not be as exciting

On my setup, I don't have isolation, I actually removed the isolators on the soekris dac.

I have the diyinhk usb to i2s board, then a potato FF and then the dac. The FF is as close as possible to the DAC i2s connector pins, to make the wiring after the FF as short as possible.

This works well if your PC and USB board are also tweaked, to provide a relatively clean usb signal.

At least that's what I used to have, I converted to a sd card player which is described in other threads on this forum.

Not sure that diyinhk did for a reclocker, but based on the potato specs, pretty hard to beat.

Here is my writeup for modding the SDP.

I stuck a potato on this board, you can look at what I did there

The end of this has what I did for the diyinhk board
