Thanks for a very nice answer. This seems like it may be a good time to start testing Audiolense.
If I understood support answer here, they are working on a fix in order to utilize Audiolense in Roon.
What I don’t know of cause is if there are some main differences in those two applications, or if one is “better” than the other. Whatever better means 
If both applications can do the same at equal quality (and SQ), it seems as Audiolense is a easier (and more expensive?) way to do achieve room correction.
I guess I would need the XO version ?
By reading Mitch book I may understand what I’m doing
But Roon will automatically pick the correct file then ?
Does this also mean I can have more than one filter for the same resolution, and choose which filter Roon should use ?
(We may see a future where we add multichannel sound from movies / TV into Roon, and we then would like to use different files)
