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 saw a demo of these at the Digital Life event. 9 out of 10 people were impressed. Unfortunately I was the tenth. It certainly appears to an untrained eye that the picture is sharper, however it introduces considerable noise as well as as blasts the contrast, and harms black level.
That being said, most people outside this forum won't know to look for this and it will be very easy for a salesman to sell these to your average lcd/plasma buyer.
