The 7007 does have the RX-101 wireless receiver, I think it is called which should do the trick. This receiver is being used in a small room, but will be moved into a larger room in its permanent location. I will, however still listen to 2 channel in there from time to time.. I will replace it with a slimline, since that is more suitable for this room. I believe it will be equipped with Bluetooth. Things in this field are changing so fast it is hard to know the right thing to do, since it can be costly.
I was going to convert songs to FLAC, then there are services offering lossless/hi-Rez streaming. Now Spotify is working toward this as we speak. Then I just saw the building of a car and a house via 3D printing. What next?
Looong story.............I had a funny thing happened last night. I gave my son 2 towers for his theater set up. He also got a slimline Marantz and I was playing Spotify from my iPhone 6. This was weeks ago. I noticed while I have been trying to make this Bluetooth thing work on the Dell laptop I kept seeing his marantz icon showing up. So I clicked on it and it showed it was playing a song. I thought that was silly. My wife was texting him at the time. I then I asked him for fun what I did...he said God Dad I was wondering what was going on...during a movie he was watching. He said unpair it please that is just weird. He lives 40 miles away...strange right?
Thanks for your time.
