fojomo the Quatros never fail to amaze me I am a fan of Vandersteens you might want to demo a pair of 2ce sigII you could fined a good price on them sense the new model is out and I would get one front end piece turntable or CD player I would do a steamer or the turntable if you are going to do tubes for the amp demo a Rogue Cronus Mag I had one with my Vandersteen 2ce sigII great combo
Enjoy the Music
