In my opinion to Focal or not to Focal is to Focal. Might check out this vid comparing the Chorus W to the Aria which I’m assuming “may” have similar voicing to the Thieva.
I’ve had Aria and currently my main speaker for the past few years has been the Chorus 836W. I’ve tried other more expensive speakers over the past couple years and keep coming back to them. This video pretty much sums up the difference I heard in my room.
