Hello,
I tried connecting my B3sepro directly to my hypex nc400 ampli, it works but at full volume the speakers "pops" and even at low volume I can tell there is a dc signal.
Is the design of the B3 se pro expect a stage output to deal with dc offset or do I need an other firmware to be able to use the B3 directly to my nc400?
I use xmos USB card and I output the dac card at + and GND.
Thanks for your help.

Yes, you really need an output stage. DC-offset is only one of your issues with direct connection. You also want some filtering to remove HF digital noise.

If you have a 9028, you can use IVY-III, Legato or Mercury.

For 9038, I recommend Mercury.
