This is my first post after reading extensively through a number of forums and my brother's insisting I get on here to better educate myself. I am entering my research phase for a new receiver and have gotten a few ideas in the $500 and under category. Most are the standard names I have read on this forum. They are the Yamamha RXV620, Marantz sr5200, Kenwood vr509 or 510, Denon 1802, and Onkyo 595. What do you guys think?? I'll most likely be hooking it up with an Energy Take 5.2 sub/sat system. I appreciate the input.
