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. ;)

Have you tried the DAC output directly? With no legato?

You don't need a dummy load, and yes you can listen directly from the DAC to your amp. AC couple it if necessary. Edited by user Saturday, December 1, 2012 10:58:56 PM(UTC)

Check the continuity on each of the PCM jumpers under the board. They should measure as if jumpers were installed (0-ohm). Brian Donegan attached the following image(s):  Untitled.png (25kb) downloaded 12 time(s).You cannot view/download attachments. Try to login or register.

When you measured that was it switched for PCM or SPDIF?

Do your refer to auto-detect S/PDIF? Edited by user Monday, December 3, 2012 7:51:46 PM(UTC)

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

What voltages do both sides of your AVCC module output measure?
