I could not test all combinations. What is sure is that the soundstage depth is really bigger. You can push the volume further without having the ears torn. I don't think the 9038 pro is a bad DAC. It is very detailed but a bit agressive with the HeKSE (it is a combination thing I guess). Seems ok with some other headphones if you read some other point of views.
About the sibilance, I solved it after a lot of research and testing. In fact I started to look at FR of the HEKse. Strangely, I found different measurements. The Crinacle tool has something magical because you can EQ live et see what's happening. So I tried. Was better, but loosing a bit of the signature. Then I tried another Fr measurement I found from reviewers. Same again, better but... hmmmm. I did at the end what I should have done the first day. I took my Umik and Rew and measured myself. I don't have the ear-like stuff to be accurate but did various tests and found a pretty nice bump at 10kHz. The things is you precisely don't see it on the Crinacle tool, big dip here. But that was the point to look at. I found someone saying to tame the 9,5khz when I read some stuff in the forum, I guess we agree. So I have a -3.0db here, with Q3.0 and on most songs now I am ok. The others are just bad recordings I am afraid. PowerAmp have this magic thing that you can choose for each track what EQ you want. So useful.
I am very happy to have my HeKSE as its full potential now. Ok, maybe not full because some will say I need a Hugo or stuff like this, but frankly it is very very good. It was before too, but as I always say, when you compare you start to see the real truth.
