Thanks. I spotted a couple of fellow head-fier owning Jubilee 25. But maybe you’re right that I’m the only one owning so many Edition line HPs. And I agree that I consider myself insane for spending this much money on Ultrasone HPs. Jubilee 25 and Edition 5 do share some tonal signatures. They are the closest among my Ultrasone collection. That said, there is quite a notable difference between the two. Jubilee 25 has better separation and sharp but sweet treble likely related to resonance characteristics specific to Macassar Ebony. I know this because I play and own an acoustic guitar with Macassar Ebony as side and back tonewood.
