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!"
It might have something to do with the fact that Samsung makes and sells LCD, Plasma, and DLP TVs with multiple lines of each while Sony has decided to only go with LCDs. No matter what you want Samsung has it not so with Sony (and for the record I own a Panasonic Plasma).
