I just bought a pioneer elite vsx-52 for $600 and a 4yr in house warrenty for $89 @ bb yest. Got it hooked up to rti a5 fronts bi-amped, csi a4 center, rti a1 rear, psw10 sub. Was using an onkyo tx-nr609 and it was good, but this pioneer is amazing. Any tweaks or how to make it more user friendly remote is somewhat challenging, and i ran audesy and it keeps sayn my rear left is in reverse phase i checkd it an its set up proper ?????
