"I had Zu Superflys in my home for several days. I found I liked them best for low level listening - really superb."
I'm not surprised. I had Zu Omens, and have Tekton Lores now. Both are what I thought of first when I read low level listening.
Horns - I would say it depends on the design. A couple of guys say yes above, but I used to own Klipschorns and I say no. It took a little more than low level volume for them to start to sound full to me in my room.
