FiiO M23 Portable Hi-Res Lossless Music Player

Like the Q15 and K19 AKM, M23 utilizes the flagship AKM DAC combo - AK4191EQ+AK4499EX. It is a new design that totally separates the digital and analog portions and also features the "DWA ROUTING Technology" to further improve the signal-to-noise ratio. These technologies allow for a purer audio background and for higher resolution audio - resulting in a relaxed yet natural sound.

For first timers on FIIO players, M23 features a switch specifically to toggle desktop mode (D.MODE). When desktop mode is activated, the M23 is completely powered by an external power source. The built in battery will neither be charged nor discharged, which ensures M23 can be used as desktop equipment without fear of damaging the battery.

On M23 there two USB Type-C ports, one of which is dedicated to accepting power only(POWER IN). When this dedicated power Type-C port is connected to fast charging, the Super High Gain Mode can be activated for more gain and more output power.

In this mode, the output power can reach up to 1000mW+1000mW per channel, making the M23 better suited for pushing high impedance headphones. While in this mode, the other Type-C port does not consume any power and thus makes it  suitable to connect the M23 to a phone for use as a USB DAC.

4-stage 20-rail power supply for accurate and consistent sound
FIIO's great experience in designing portable HiFi audio player power supplies is in full show on the M23. With a four-stage and 20-smaller rail power supply, the M23 is fully equipped with a robust power supply that provides a solid foundation for both the analog and digital portions of the audio circuit.
