It does sound very good! Hard to find a closed back with the "full package". I love the bass of my Cascades. I love the detail and imaging of my LSA HP-2's. The Elegia's are a nice compromise, but not Great at one thing. The T60 Argons are my least favourite closed backs.For me, the R9 is just a true fun provider. Its bass is just huge, the overall sound is very clear and forward sounding. When I'm listening to something like Black Sabbath, Post Malone or basically any modern music, I have so much fun that it's kinda intoxicating.
My girlfriend stole the R9 yesterday for like 3 hours, she was laying down with the R9 + Bluemini R2r plugged into and she said that she had that revelation when "you want to listen to every song you know again". If that's not great, I don't know what is
How would you rank the R9's using the criteria from your big comparo?
