I have the Sopra 2's paired with Simaudio 700i. Huge soundstage, room filling vocals, when the artists intent was to have a huge soundstage. Can and will be more narrow and focused when the artist recorded that way. The speakers are very representative of how the material was recorded.
What Dan Bejar song (Destroyer album or TNP?) are you referring to I will give it a listen and let you know how the soundstage and vocal height is on my system.
I have had my Sopra's a year now, they get better with mileage and continue to improve, at about 350 hours now I would guess. Have read they need over 400 to settle in nicely. They sound amazing now and much better than when they were delivered (although sounded very good when delivered, but tight). They also love the Simaudio 700i (what a beast), however my Hegel 300 also worked very well with the Sopras.
Hope this helps.
