Ha! The new controller works to power everything off and on with one button, and I can control the volume of my receiver with it too! I just eliminated 1.5 controllers! Thats pretty cool. It's working just as good as the wired connection did. No drops or lags. I have pretty good internets and an older but decent router, and it's right next to my receiver.
.5 because I still have to use the Marantz remote to switch inputs. Don't need it for power and volume control anymore tho!
