I'm surprised no one has mentioned this so far, but I'd highly recommend at least nailing down if not outright purchasing your speakers first. At this level all the integrateds you'd consider will be very good. The only remaining questions are which one sounds best TO YOU and, just as importantly, which one is better capable of driving and which sounds best to you with YOUR SPEAKERS. Case in point, would one amp sound the best with both the AZs and the Vandys? Maybe, but probably not. They're very different designs and loads. Anyway, just wanted to raise this as a potential issue, and best of luck in building a great system.
