AKM flagship DAC combo
AK4191EQ AK4499EX

Like the Q15 and K9 AKM, the M23 utilizes the flagship AKM DAC combo —— the 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.

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 AAA 78+ 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 caliber 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 caliber HiFi components flowing with quality
The I/V, LPF, THX amp parts of the audio circuit utilize 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.

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 is used to safely allow for up to 30W charging speeds. When the battery gets close to a full state of charge, the M23 switches to slightly slower normal 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.

DAPS Digital Audio Purification System, Bit perfect
The DAPS (Digital Audio Purification System) as featured on the M23 consists of both the FIIO-developed HiFi audio core that bypasses the original Android version plus a low-jitter clock co-processor. Together, the system not only provides a unified high-precision, low-jitter clock source but also ensures that the original sampling rate of the audio stream (both PCM and DSD) is preserved no matter if you are using FIIO Music, third-party apps, USB DAC mode, etc. By avoiding audio resampling, you can be sure the audio is that much closer to its original intent.
