I'm considering used Vandersteen Quatro

Agree on the VAndy info all are giving.  Glad you went with the 2's.  You'll  love them I'm sure.  I'm running the Ayre AX5 Twenty with my Treo's and am trying to sell the Treo's for the Quatro's.  I will just install the filter on the inputs and manually plug in the balance out from my Rhea or the Balanced output from my Empirical OSDE/SE.  Not the best solution, but it works easily and I'm always up to put on a record so it's easy.

Recently heard the Vandersteen Quatro CT's. Liked 'em. Very much

BTW- John at Audio Connection is a very good guy to deal with- 

Guys, I've sent a few folks to Johnny in the last couple of years and they all have been very very happy.  Jetson is included in this.  He just understands how and why things sound good together.  Yes, he loves Vandersteen, but he also sells Proac, Maggies, B&W, NOLA and many others.  He also understands your listening room and inexpensive ways to improve your sound.  I've never heard a bad word about him.  It's rare to find someone who is more willing to help even if it means nothing in his own pocket.  Yes, I think he's the top dealer in the country to deal with that I personally have met and I've been to a lot of places and met a lot of great dealers.  Just have never found anyone better IMHO.
