Audiophiles rejoice — this is the best sounding dedicated iPod speaker system in the world. Unfortunately, it’s also the most expensive. The Klipsch iFi ($99) features an iPod docking station, two Klipsch Reference Series RSX-3 satellites, and an 8-inch subwoofer with a built-in amplifier that offers 200 watts of peak system power. The iFi also comes with a small radio frequency remote that can send signals through walls. It’s compatible with all iPods with bottom dock connectors, but older iPods and other portable audio players can be played through their mini jack.
