First tests done 
Even though I don't understand all the settings yet, I got quite good results already. Now listening track by track with a smile in my face. More clear articulation, better soundstage, more easy to listen to. I must have got some frequencies played too loud because of my room response. Setting and testing the target curve again is a fast process -at least compared to Sweet Room. (I am using Roon in a nuc.)
I did the room measurement with the laptop (easy to carry to a different room), and did the filter design in my daw workstation. First, I installed the Impala too old/cheap laptop. Impala installed ok, but did not start at all - no error messages were shown. With the quick help of Focus Fidelity, the reason was found. My laptop's cpu was missing AVX instruction set. So, I needed to use better laptop. After that, everything went smoothly
