Summary: Vita Audio elbowed its way into the crowded DAB market with its simple and sonically-superior range of radios. But it’s not ready to stop there: the new R4 is a complete tabletop hi-fi system and its most ambitious design to date.

As befits a music system for the modern age, there’s also an iPod dock. Still after more features?
