AKM flagship DAC combo

AK4191EQ AK4499EX

Like the Q15 and K9 AKM, the M23 utilises the flagship AKM DAC combo – the AK4191EQ+AK4499EX. It is a new design that totally separates the digital and analogue 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.


Patented desktop mode activated with one click

For the first time on FiiO players, the 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 the M23 can be used as desktop equipment without fear of damaging the battery.

Independent Type-C power port

unlimited power

On the M23 are 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.

All new THX AAA78+ amp design truly balanced 8-way parallel amplification

The THX AAA 78 headphone amplifiers as used in the M11 Plus and M11 Pro have been widely praised by audiophiles around the world. After several years of continuing to refine the design, we introduce the THX AAA 78+ amplifier architecture in the M23. It allows for greater power output with high fidelity, resulting in powerful sound reproduced with extreme accuracy.


High calibre HiFi audio architecture 4 gain levels

In the M23 is a high caliber audio architecture consisting of DAC, I/V, LPF, voltage amplification, and parallel amplification stages. Responsible for handling the I/V and LPF stages are 2 low-noise and high-precision OPA1612 op-amps. The voltage amplification is taken care of by 2 low-noise and high-bandwidth OPA1662 op-amps. Together, these op-amps ensure audio signals are accurately played back at ample power outputs so that a huge variety of headphones and IEMs can work well with the player, which can be further better dialed in thanks to the four levels of gain.


High calibre HiFi components flowing with quality

The I/V, LPF, THX amp parts of the audio circuit utilise a large number of high-precision film resistors. The LPF section specifically employs 8 Panasonic film capacitors. Together, the capacitors ensure a highly detailed and also highly stable sound, as they help to make the left and right channels output as well as output of each frequency band more consistent.

*The components are distributed under the audio shield cover.


Dual-mode fast charging

Safe 30W charging

The M23 employs a dual-mode fast-charging system that utilizes extreme fast-charging + normal fast charging. At a lower battery state of charge, extreme fast-charging, which allows for greatly improved charging times while still maintaining battery health.


Large 5500mAh battery durability incarnate

Specially selected low-resistance fast-charging batteries that employ high-temperature resistant material are paired with technologies such as a low-resistance MOS protection board to ensure the batteries will last a long time.
