Vandersteen Quatro CT or Wilson Sabrina

Sorry to add to the Vandersteen recommendations, but I, too, think the Vandersteen's are superior to the Wilson's. Make no mistake, I listened to a pair of Sabrina's and was very impressed, but Mr. V. has been around a long time, answers questions personally and builds his speakers to last.
I own the Treo's(non-CT), and love them. If I could afford the Quattro CT's, I'd get them in a heartbeat.

@tomic601 ,
From my experience with the 2wq subs in my home, I do not find the bass notes traveling beneath to the basement, so unless your condo is built with minimal insulation, I think you wouldn't incur the wrath of your neighbors.
