You’ll never be short of something to listen to with this sleek mini-system from Onkyo. For starters, the top-loading dock for iPhone 5 plays locally stored MP3s and AAC files along with your desired cloud service selections. Legacy iPhones and iPods, other compatible smartphones and tablets, and flash memory drives filled with music are connected via the direct-digital-capable USB port. There’s a DAB/DAB+ tuner offering a wide variety of content—with 40 presets for your favorite stations—plus a handy FM tuner. Rounding out the package is a smooth tray-type CD player (which also handles MP3-encoded discs), and an analog input for other media players. Once you’re cued up, get ready for a pleasant surprise: rather than the muffled, flat reproduction you expect from some all-in-one dock systems, the CS-255DAB projects well-separated stereo sound across a wide soundstage, with punchy bass, lively dynamics, and plenty of detail right across the audio spectrum. This is thanks to the efficient digital amplifier and solid bookshelf speakers, which, like the stylish receiver, show the world that you’re serious about sound.
