I got the RP set up to work. I don't know what changed, but I just tried plugging it in again after a day of wondering if I'd have to wait another week to get it resolved, and it worked!
I did the set up and am now in critical listening phase. I won't go too in depth in my assessment until I have had more time to listen, but I will say that so far it sounds really good. I might redo the RP setup as I'm not sure I did it as well as I should have. I failed to read the instructions fully, especially the part about pointing the mic in random directions. When I set it up I pointed the mic between the speakers, regardless of the position I set the mic in. I think the sound might get better if I redo it, and other than the time it takes I really don't have much to lose.
