Sony Altus
Wiring your entire home for sound can be a huge pain — especially if you're working on a historic or otherwise pre-existing residence — which is why we're intrigued by the Sony Altus ($50-$700) system. Utilizing 2.4GHz wireless technology, the Altus system can push audio from the source of your choice, be it a stereo, TV, or iPod, to a maximum of eight separate speakers around your house, letting you "Party in the USA" no matter where you are. If that sounds a bit rich for your blood, there's always the Rocketfish system, which also uses a 2.4GHz wireless audio standard but runs from $60-$200. [Thanks, Todd]
