If you're a fan of analog radio, then Polk Audio's new I-Sonic ($600, available in September) should be on your Christmas list this year. The compact system offers HD Radio technology for static-free reception — AM sounds as good as FM, and FM sounds like a CD. The I-Sonic also Plays DVDs, CDs, Picture CDs, Video CDs and MP3 CDs, and is XM Satellite Radio ready. It has an auxiliary input for your iPod, a dual-alarm clock radio, and 30 radio presets. And since it's Polk, rest assured the compact system will offer rich, room-filling sound and tight bass.
