US reviewer Michael Berk has taken an in depth review of the Arcam rCube and, despite his initial suspicions, concluded, “It sounds significantly better than you'd expect from device this small.”
Michael also spends considerable time testing the rCube’s wireless streaming via the rWave and rWand and its stamina running from the internal battery. He noted “You're not tied to an outlet, you can pass the rWand dongle around between iPhones and iPods, streaming lossless files for hours and hours without blowing through your batteries. And it looks good doing it.”
