out of the 3 you listed i would say the Yamaha.. had a buddy who had a yamaha reciever andhe freaking loved it, couldn't say enough good stuff about it, i almost bough a Yamaha, due to the how much he liked his..
if you trying to stick with in the same price range, all the manufactur's are going to be about equal, look for the product that has the options that "you" want, i would advice getting the fewest options that you need as possible, dont get one because it has 30different modes of surround sound, get the one that has the better processing, even if it only has mabe 3 modes.. you will enjoy those 3 modes, way more than you ever would the 27 modes of the other, that didnt sound as good...
hope this makes sense, and mabe even helps you chose your product..
