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!"
Well, it's still costing them money since they have two transmitters running, for the most part. That's why you're starting to (and will see more) stations who decide to pull the analog plug early and save more than a few grand in power bills. And there's still some stations who aren't passing through network HD either. Of our three network affiliates, Fox airs all their network programming in HD, the NBC only airs live network programming in HD, and the CBS has yet to air anything in HD, and the CBS says they 'might' be able to do some HD before February. (ABC here is a .2 digital subchannel from the Fox station)
