Let the hive mind of Engadget get that for you.
"What is the best wireless surround sound speaker solution? I have a home theater where running wires is just not feasible. I have my own speakers, so I don't want a system that has speakers with integrated wireless. I've done a far amount of research and have only come across a few companies that even offer a reasonable solution: KEF, Kenwood and Rocketfish. Is there anything else out there? What do you recommend? Thank you!"
Which makes it more of a reason to buy a PS3 instead of a stand-alone v1.0 or v1.1 BD-Player. I am happy to have mine for the cost of $0.00 (gift purchase) and a 60GB version :)
