I'm looking for a reciever for my first real HT setup. It is going in a relatively small room (12x15ish). It is going to have an HDTV, Xbox 360, and who knows what else hooked up to it. For speakers, I have been looking at JBL's E-series. I have been looking around the 400-500 price point. This is what I have been looking at. -Yamaha HTR-5890 -Yamaha HTR-5860 -Onkyo TX-SR603 -Onkyo TX-SR703 -a couple Marantz units One question I have is what are the main differences between the two units for each brand up there other than power? Being in a small room, it seems the lower powered unit of each company would do just fine. Also, this will be used for 50/50 movies/music. Any recommendations or info would be appreciated.
