I own 4 AV receivers, but I am moving and can only keep one. Let me start, HDMI and Atmos are not a priority or the deciding factor 1. 2002 Sony STR-DA7ES, 2. 2004 Yamaha RX-V2500, 3. 2004 Pioneer Elite VSX-55txi, and 4. 2016 Onkyo TX-RZ810. Which one should I keep? And I'm not selling all of them and buying a Denon/Marantz, before someone tells me to do that. I can only keep one.
