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 was sold the U400 package with the "Look at ALL the SPORTS channels!!" sales pitch. We LOVE sports in our home. Reality: nearly ALL live sports broadcasts are blacked out, so you don't get to actually WATCH any live sports on those channels. For instance, on Saturday evening, we could not get any Hockey or Basketball games. NONE. ALL blacked out. What good is having sports channels without the games? The literature has double asterisks by each channel **. The foot note states that the channels are subject to blackouts. So... Beware. You're not getting what you think you are.
