Something wrong with the sound happened in the new system

hey, something wrong with the sound happened in the new system... Every time i switch to a new system i hear this annoying sound which is more compressed, harsh, flat, uglier. As if it lacked resolution... I recorded this example one by one via XLR to my RME UCX interface. I can't hear the difference when I reamping direct track…

I have owned a Kemper for 3 years and have never experienced anything like this before. I love my stage and I will stay with it even on old OS... but I feel disappointed... What do You think?

Did you change your low and high cuts or adjusted any clean and dist sense? New battery for a active pickup? Changed the high cut on the delays? etc.

No changes. Everything is the same. I checked twenty times!
