The Soundcast iCast ($299 list) is the latest in a seemingly endless line of iPod docks, but this is the first I've seen that transmits audio wirelessly to a receiver that you can connect to your home stereo. The transmitter charges your iPod and provides an auxiliary line-in port and headphone jack. The receiver gives you basic playback controls and analog RCA outputs. The special thing about the iCast, though, is that despite its reliance on the 2.4-GHz frequency band, it does not bow down to interference from anything. Thanks to an automatic frequency-hopping feature, the sound quality is crystal-clear even with the unit parked right in front of a running microwave oven. That's a feature I wish all wireless products had. Each transmitter can broadcast a single audio stream to up to two receivers (sorry, no multiple streams).
