I'd like to extend the sound from one room to the rest of my house with wireless speakers. What do I need to buy? I have a fairly new Denon Receiver which is connected to several wired speakers in one room. I'd like to option of same audio throughout or different in one room to the next (if that's possible -- i.e. TV in family room; music in living). I'm not technical and got suckered into the Denon to replace a very old Bose Lifestyle. One of my asks was easy scale, wirelessly to other rooms and we didn't quite get there. Can someone suggest? Do I need the CONNECT and speakers or just speakers?
