Your image export and your straight line are two different things.
Can you save, zip and post one of your REW measurements here?
@Marconi. Yes, I believe so. I remember bypassing the analog section eliminated the higher harmonics. The AKM DAC is pretty good.
Hello there, what are the cheapest/fastest mods to do on the DCX knowing the fact that it is connected via XLR in inputs A/B/C from my EMOTIVA CMX2 and feeding 3 bi-amp speakers (low/high filters).
the thing is that I have some ground noise that I would like to get rid of.
Thank you in advance!

Tojoko, thanks for the measurements, I am able to open them no problem.
But I don't understand what is going on here. The noise floor in the second measurement show spikes that do not look mains frequency related. Overall distortion is low, but it looks very spiky. Maybe it's a clock problem?
What are you using to get the digital signal to the DCX and what are you using to get the analog signal back into REW?

Yes, that's what I meant. The DCX is meant for pro line level which is a good bit higher than consumer line level. That means that if you are using the analog inputs your signal levels will be low compared to the noise levels. That might be what is causing your ground noise, or at least making it more obvious. Are you going in and out balanced?
Gain structure is important, and can be difficult with the DCX.

The DCX is basically unity gain from in to out. But it's made for a hot signal such as would be coming from a mixing console. If the input VU meters aren't hitting near red on your loudest peaks, then you'll run into noise problems.
You might also have a ground loop, although I've found the stock input to be robustly immune to hum and buzz in balanced mode. If you are coming from an unbalanced source there are several different ways you can wire the input. First check to hear if the buzz goes away if you disconnect one or booth inputs.
