When I compared my REW measurements to Dirac (screenshots) they were quite different. I think it’s the multi point combined with some psycho acoustic logic. I was able to get reasonable results eyeballing PEQ to the Dirac screenshots. REW calculated ones weren’t so good. It’s a complex topic.
I dream that one day Dirac will be native in Roon…
Meanwhile PEQ is ok for me.
I think the biggest issue in my system is a bass suckout which makes the overall sound thin. EQ does a great Job.
