Just a FYI, it looks like the Sony NT-5 will be able to have wireless rears too, after an update coming out sometime this month. The quality should be a lot better than the RT5, but it's only 4.1 surround sound with the rears and not 5.1. There is also a lower model sony that can apparently also do the wireless rears, that would probably be more on par with the RT5 (the NT5 will be a big step up).
I created a new thread for it, just a FYI!
Guys can anyone comment on the performance of the rear speakers as surround enablers for the HT-RT5? They are almost uncovered in this thread. Do they offer a rear sound stage with unique sounds for unique channels? Are they very weak and of low volume?
Thank you
