I have an Onkyo TX 8050 receiver with two wired speakers. I am thinking of adding wireless speakers to play the same music (from my turntable and CD changer) in another room. I would also like to stream from iPhone/iPad without having to plug into USB. Is there a Bluetooth transmitter/receiver that I can use for this? Would I need anything else? I found the Bluetooth dongle manufactured by Onkyo, but it doesn't seem to help with adding the speakers, and it's frightfully expensive! Any help is much appreciated!
