Hi Rick,

We've reviewed a few HTiBs with wireless speakers

but nothing in terms of separate speakers yet. I haven't heard of anything really different from these on the horizon. Kenwood, for example, showed a system that allows you to plug any speakers into a small amplifier module that receives a wireless broadcast from a base station, but its power is pretty limited.

One of the main problems is that you can't transmit power wirelessly with any effeciency, so most wireless speaker solutions still need to plug into a wall outlet or, yes, run on betteries.

We'll keep an eye out for more such systems.
