Back in the early 2000s I used to love Sony AVRs, installed a ton and even worked for a “Sony Only” store. The fact that the AVRs wouldn’t do all channel stereo in any shape or form always bugged me so eventually I stopped using them. Guess I still have good reason to stay away :(. IDK what their reasoning could possibly be for doing that. Shame because I loved the build quality and controllability. Also always bugged me that there were no rear control ports.
