Look mom, no wires: Audioengine AW1 wireless audio adapter review {Engadget HD}

Apr 10th 2008 2:23PM I have a question regarding the AW1 ~ how does it work for rear surround if you have a receiver that is outputting a 'powered' line for a wired speaker? is this not a good idea?

would one need to get a receiver with line-level outputs?

thanks for any reply!
