Direct profile Behringer DI causing flubbiness?

I'm going to do another test. Mic up the guitar cab so you can hear, real amp vs behringer profile vs kemper profile
See if that helps! haha

Using a spectrum analyser both the Kemper and the Behringer DI are similarly linear! However to my ears, I prefer the profiles I've created with the Kemper.

It was really hard for me to get the levels all the same micced up and make a really good comparison. I think the Behringer is sufficient though. Some might say just as good, but not me (-;
