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!"
Also, the earlier price was correct, I didn't see that the ATI Wonder card is additional $300 until I configured a PC to see what would be necessary... mine ended up being $3,259. Not with Vista... not for me. I'll stick with XP, it runs faster.
