"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!"
Most of the Japanese recorders are DVRs too. A HDD for recording shows and then the BD drive for archiving or playing them back. Don't ask me why the Japanese are so enamoured with recordable media but clearly they are.
