First of all amazing forums you guys have here I have learned a lot from reads posts. I recently purchased the Jamos 426 HCS 3 speakers and have done a lot of searching for receivers: and I am between the Onkyo 616 and Yamaha 473. I am leaning toward the Yamaha due to reviews but the THX certification on the Onkyo keeps staring at me. I am looking for a receiver for movies and Video games mostly and am concerned about the Yamaha having enough power to supply the speakers during the loud explosion scenes of movies. I have done some research on here and someone said that you are supposed to have twice the wattage of your speakers since it better to have more than less. I am quite the newbie when it comes to understand rms wattage vs 100 watts at 15khz and all of that stuff. If you guys have any input on if the yamaha would work or have another receiver I haven't heard about in the $400 range I would be very grateful.
