Makes sense. Based on your reasoning and what you've seen in the config text, it seems that the order of operations is correct and I probably should not include anything additional in the hesuvi app to avoid redundancies. Thanks!
Sure, here is the hesuvi text file.
Hello! I have a question regarding the proper set-up for using a PEACE preset EQ alongside HeSuVi for the same audio source. The attached screenshot is the configuration I currently have for the Pro X Wireless headset (since the built-in DTS Headphone:X is absolutely awful). Do I need to add the peace.txt config to the beforehand or afterhand fields? I noticed that if I do, it doubled or tripled the preamp decrease.
