Damn, that's it!? Did you get it online or in the store? Open box?
Sounds like a great price.
I looked further into it and my interpretation is apparently correct. If you choose to use BOTH wide and height, you need to make that specific choice in the Speaker Config menu, then the GUI will show that you now connect the Wides to the Back Surround outputs. I have to assume that the signal sent to those outputs is properly decoded from the front. However, this also means that I have to recalibrate the XT32 in that configuration, as there is no "memory" feature to save the previous configuration. If they are going to make me change speaker connections, I think adding a memory function for the XT32 would have been nice in case you choose to switch back and forth depending on material.
