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!"
I sort of agree with Mike. I don't know how much the firmware updates on the HD-A1 help, but if they are significant, you can pick one up for $300 now! I must say, seeing all the HDi functionality and future planned network features of HD-DVD at CES, I am getting closer and closer to picking one of them up myself!
