New FiiO portable music player offers desktop-grade hi-res audio on the go

Having recently impressed us with their mid-range FiiO M11S portable digital audio player, Chinese audio firm FiiO is back with a decidedly high-end offering for its next on-the-go device.

The new M15S portable player comes packed with two desktop-grade ES9038PRO digital-to-analog converters, with individual DAC chips dedicated to the left and right stereo channels.
