Truth be told, the world probably isn’t in need of another compact DAC/headphone amp, but then Arcam’s MusicBOOST is no ordinary suit-pocket-sized sonic boon. Designed to accommodate Apple’s duo of flagship iPhones, the integrated design combines genuinely audio-enhancing circuitry from the Texas Instruments/Burr Brown R&D stable with a handy mobile power supply equating to 120 percent of extra battery life – allowing ample opportunity to catch up on all things Brogue while you sample the euphoric chords of DJ Shadow’s forthcoming release, The Mountain Will Fall.
