So Many Choices, So Little Time
The Yamaha RX-V1500 powers my 5.1 system. I haven't looked at the other receivers, so I can't give you any advice that compares the three receivers. All I can say is that I'm satisfied with my receiver. My last receiver was a Yamaha RX-V596. I liked it, too. In fact, I would still use it but I wanted the newer technology available on the 1500, including video component ins and outs, etc. I agree with those who say that receivers in the same price range are equivalent in their sound. You should look for the features that make your system work most efficiently. Trying to compare the sound output of receivers is impossible because too many variables can't be controlled. The setup you listen to in the store is not like your setup at home so the sound comparison is impossible to make. Buy the receiver that has the features you want, at the price point you're willing to meet, and that looks the way you want it to look. Then, be happy. Until the next time you're ready to upgrade.
