Very likely the signals are simply different. You would need to check the actually digital signal.

I added flux in all jumpers & resoldered, it seems now isn't a lot of difference between between channels using S/PDIF or I2S, also the left channel seems to sounds louder (still not louder as right channel but the difference isn't than bigger than before).

I misunderstood what you meant. I thought you were saying the the SPDIF signal was overall louder than I2S. ;)

Yes are overall louder but still right channel sounds a little bit louder & the same happens with I2S.

You don't need a dummy load, and yes you can listen directly from the DAC to your amp. AC couple it if necessary.

Check the continuity on each of the PCM jumpers under the board. They should measure as if jumpers were installed (0-ohm).

No continuity in each of the 3 JPCM, without Sidecar connected.

With Sidecar connected:

JPCM1 69.5K
JPCM2 93.2K
JPCM3 69.5K

The sidecar would need to be powered for the relays to engage.
