I changed my soundcard Realtek S/PDIF for a Creative CMI8738-6ch analog and the filters don't seem right. Is this a good enough reason to generate new impulse filters?

Attached are my measurements made with the Realtek (1-6) and the Creative Tech (7-13). I calculated the difference (A/B) and you can see the curves as 14-19.

Thanks.

Strange to reply to myself, but it may help someone else.

Do it! Don't hesitate. Filters not designed for your hardware is usually worse than no filters at all. After replaying my test file with the new filters in place, the difference was phenomenal.
