You picked a good shop to visit. I also use them exclusively, and you'll never be disapointed with their service. I've bought my 600's, 604's and ASW 750 from them without any problems. Regardless of what people may say about B&W, the 600 series offers excellent sound at a great price. I haven't heard much from boston acoustics so I'm not much help, this was just a rant about you going to the best shop around.
