The Bottom Line Though it does include an HD Radio tuner at a fairly low price, the no-frills iLuv i168 doesn't offer much to distinguish itself from the clock radio competition. The 820HD is a top-notch tabletop clock radio with support for the latest all-digital HD Radio format. The Polk Audio I-Sonic ES2 pairs the same excellent sound as its predecessor with an improved design--but we would've liked more features at this price.
