I'm just getting a foot in the door with a real home theater system and while I'm trying to do this on a small budget, I do still have some questions regarding power ratings and wattage across the system. The receiver I've been looking at is the Denon AVR-E400. The speakers: Monoprice 10565 (I said budget didn't I?) I'm just looking for some insight into what is compatible with regard to wattage. Power requirements for the speakers and power rating of the reciever. Would that system above be compatible? What's a good rule of thumb when selecting a reciever/speaker set? I appreciate any feedback.
