This young company has hit the ground running with its first portable DAC and headphone amp. Supplied with all the cables needed to connect digitally to your mobile device, it sports an optical digital input alongside USB. Audiophiles will love its balanced headphone output alongside the regular 3.5mm jack socket, and its ten-hour battery life. High quality ESS DAC chips serve up a detailed and vivid sound, and its rugged aluminium casing is one of the most stylish around. For music on the move, it’s a terrific choice.
