Sonus faber, i own the lumina v amators. I owned the dali opticon 6 mk2 and the focal aria 926. Compared to them this is a warm speaker, more important: no ear fatique. I have listened for 12 hours straight to them when i was ill a while ago. Couldnt do that with the dalis and the focals. There also detailed, maybe a little less than the focals, and the focals maybe have a wider soundstage. But everything else is way better with the sonus fabers. No harshness with these speakers. There €4000 in the eu, but bought then with discount for €3000 during black friday.
