FiiO M15S Digital Audio Player Hands-on Review: Flagship Portable Sound

I'm sure FiiO will be pleased with me disagreeing with their market positioning of the M15S. While the company refers to it as a sub-flagship portable music player, I'm making the case that it is, in fact, the flagship DAP. This is due to its significantly higher level of portability compared to the M17. Furthermore, its flagship status is reinforced by the inclusion of a desktop-grade DAC chip and an exceptionally precise and refined physical volume knob.
