At $500, the Polk isn’t exactly cheap, but this four-speaker unit packs a considerable sonic punch considering its size and fills rooms with sharp audio in a way that eludes more inexpensive iPod speaker systems.

The Good: Huge, tight, room-filling sound packed into a compact design. Auxiliary input enables general sound system use. Displays station signal strength, stores presets. Includes cradle adapters for dockable iPods and iPhones. S-Video and composite outputs play device’s stored video on a television.

The Bad: iTunes Tagging can’t name every tune, only works with 5G video iPod, 3G iPod Nano and iPod Classic. No display on remote, Wi-Fi or internet radio.

The Bottomline: We just wish this thing were capable of handling internet radio streams too.

Price: Starting at $500 .
