Well, I have the XPA-3. FedEx Ground tried to deliver when I was in the shower, but thankfully the same guy delivers to where I work at the hospital, so he had me sign there and took it back to my house. It's all hooked up and works. Well, I haven't tried anything using the center channel yet. The only issue is there is a distractingly loud hum now. I'll have to see what I can do about it.
