Upgrade from DeVore Gibbon X

I have happily owned these speakers for about 6 years now; during this time I have patiently upgraded my front end, with the Gibbons successfully conveying each upgrade.  While I am very happy with my current system, I am now wondering if a speaker upgrade is in order.  I am interested in some input from anyone who has upgraded from the Gibbon X or someone who has had significant time comparing these speakers to other offerings.  Wilson Sasha DAWS? Magico? I am running an all VAC front end (100W/ch) in a 17 X 19 room.
