Hmmm...well.. as I own Q3, I love my Magico and have not heard anything near its price range that I love better. For what's its worth, I heard Vandersteen 7 under show condition and in a dealer showroom (where I heard Magico V3 many times) and thought that V7 was nice but if I have the budget now, I would not replace Q3 with it. Recently, another friend auditioned Q3, Sonus Faber Amati Futura, Rockport Avior extensively in his home. I heard Futura there briefly and thought that it beautified everything and really put its sonic signature forward strongly. Some friends like that but I was not one of them. At the end, my friend also chose Q3. Unfortunately I did not hear Avior there but heard it in a different room later.
I never heard a system under show environment that let me hear the full potential and when I come home, I always feel very good listening to my system right after hearing those big Wilson, Avalon, Scaena, YG. So I would not judge Magico or anything for that matter under those condition.
