Portable Desktop-Level Machine

The “desktop/portable dual power supply modes” as featured on the portable desktop-grade player M17 and the portable desktop-grade amp Q7 have been well-received by the audiophile community, which is why we sought to put this technology on other products. Now, with the implementation of the dual power supply modes onto the M15 with its more ergonomic design, the M15S is the ideal combination of portability and high performance.

Dedicated Desktop Mode

When in the dedicated desktop mode and under USB fast charging, the M15S will transform essentially into a desktop device and work completely without the battery. That is, under this mode the battery will neither be charged nor discharged, preventing premature battery degradation.

High Performance ES9038PRO DAC

The full, uncut desktop ES9038PRO DAC chip with eight independent D/A converters is employed in the M15S. Each channel uses four D/A converters in parallel to form a fully differential output, for a truly rich and highly resolving sound.

4th-gen FPGA+NDK femtosecond crystal DAPS purification system

Audio data is passed through a FiiO-developed 4th-gen FPGA with phase-locked loop technology, which works together with two custom Japanese NDK femtosecond crystal oscillators to provide a high-precision and low jitter unified clock source for the entire audio architecture. This is all done in the pursuit of purer sound.
