I love the Maggies. Mainly I'm looking to downsize a bit. If I had one complaint about the Magnepans acoustically it would be the sweet spot is pretty location dependent. If I am on the couch they sound amazing, but standing or off center in the room and they loose the high end a bit. But the main reason for the upgrade is to get something a little smaller and eliminate the need for a Sub.
I compared 4-5 different speakers at the dealer; Martin Logan Theos, KEF LS50, B&W 684s, & the Viennas. Liked them the best, particularly for the $$.
