Because of the odd shape of my HT room, I can't place the rear surrounds the same distance apart from the main listening position. So I am leaning toward getting a receiver that allows individual adjustments for the R and L rear surrounds. Of the AVRs I am looking at, the Pioneer VSX45 allows separate settings. The Yamaha rx-v1300 and 2300 don't appear to allow it. Not sure about the Nad T751-61-62 line, or the Marantz 7200-8200, Denon 3802-03. Can any owners of those AVRs tell if they allow separate adjustments?
