Pkancel, if the Scala had more mid bass than the Sasha, I would think it would be more difficult to position.
In my room, I have to EQ the Sashas @75hz down about 9db to get rid of the hump.
I had a quick audition of the Scala today at a dealer, but the setup was problematic (in a crowded room with the speakers on each side of a massive, three-column equipment rack). Midrange/treble was gorgeous, no edge at all (although it didn't seem overly extended in the high frequencies), but bass was all muddy boom (again, non-optimal setup)
Would love to hear more details of your head to head, i.e.
1) what size is your room
2) what electronics
3) what media you used/listen to
