A couple of questions: 1) Which is more important to focus on when buying a system from scratch? The quality of the speakers or the quality of the receiver? 2) Of the following receivers which would you recommend based on its musicality? Marantz 8200, Pioneer 47TX, Denon 4802? 3) If I don't plan on building a THX standard setup anytime soon does it make more sense to buy a receiver without this feature and put the difference towards something else?
