Following the Q15 and K9 AKM, this is the third time the FiiO portable player has adopted AKM’s new flagship DAC duo – the AK4191EQ + AK4499EX. Based on a newly designed fully separate digital/analog structure, it incorporates the newly developed DWA ROUTING technology, improving the signal-to-noise ratio and reducing noise of various amplitudes, further purifying the background, enhancing resolution, and delivering a balanced, relaxed, and natural sound.
Patented Desktop Mode – One-Button Activation
For the first time, FiiO portable players feature a high-efficiency desktop mode (D.MODE) switch. When desktop mode is activated, the M23 will be entirely powered externally; the built-in battery will neither charge nor discharge, allowing it to be used as a desktop player, effectively extending battery life.
Patent No.: ZL202321946664.8
Independent Type-C Power Supply, Unlimited Power
Features dual Type-C interfaces, one of which is an independent power supply interface (POWER IN). Connecting the independent power supply interface to fast charge activates the headphone mode, further releasing amplifier gain and driving power, achieving an output power of up to 1000mW + 1000mW per channel, better driving high-impedance headphones. In this mode, the other Type-C interface consumes no power and is suitable for connecting to a mobile phone as a USB DAC.
The THX AAA 78 headphone amplifier technology used in the M11 Pro and M11 Plus is beloved by users worldwide. After years of refinement and improvement, it has been innovated into the THX AAA 78+ headphone amplifier architecture, significantly increasing the output power of the M23 while delivering studio-level sound reproduction, immersive and powerful sound.
Full-Link HiFi Audio Architecture: Hybrid Four-Level Gain
Featuring a complete audio architecture encompassing DAC, I/V, LPF, voltage amplification, and parallel drive, the I/V and LPF sections each utilize two low-noise, high-precision OPA1612 op-amps, while the voltage amplification section employs two low-noise, high-bandwidth OPA1662 op-amps. This ensures accurate audio signal reproduction, clear detail resolution, and significantly enhanced driving capability. Combined with a hybrid four-level gain, it further expands the driving range of the power amplifier, better adapting to in-ear and over-ear headphones.
Full-chain HiFi audio components
The audio circuitry for I/V, LPF, and THX uses a large number of high-precision thin-film resistors, and the LPF section also uses 8 Panasonic thin-film capacitors, which enables delicate and stable sound quality and higher performance consistency across the left and right channels and frequency bands.
Four-Stage, Twenty-Channel Ultra-Refined Power Supply for Precise and Stable Sound Reproduction
FiiO’s years of experience in portable HiFi audio power supply design are fully realized in the M23. The M23 features a four-level power stabilization architecture and up to twenty branch power supply networks, providing a solid foundation and power for high-quality digital and analog audio.
Independent Analog and Digital Power Supply
Effectively reduces crosstalk between digital and analog circuits, resulting in more accurate digital audio, purer analog audio, and more powerful drive. Analog Audio Power Supply: The analog circuit power supply not only features multiple independent power supplies for DAC, small signal amplification, and headphone amplifier drive, but also employs a four-stage series voltage regulation architecture including OVP, self-adjusting regulation, high-efficiency boost, π-type filtering, and LDO regulation, providing a power supply network comparable to desktop systems in a portable desktop.
28 High-Capacity Polymer Tantalum Capacitors
In the refined power supply system for DAC, I/V, LPF, and THX, the M23 is equipped with 28 high-capacity polymer tantalum capacitors, providing strong power supply, ample energy storage, and a more powerful sound.
Analog power supply: 4 KEMET high-capacity polymer tantalum capacitors
THX power supply: 12 KEMET high-capacity polymer tantalum capacitors
I/V and LPF power supply: 6 high-capacity AVX polymer tantalum capacitors
DAC power supply: 6 KEMET high-capacity polymer tantalum capacitors
Dual-Core Fast Charging Engine, 30W Safe Supercharging
The M23 utilizes dual-charging engine technology—combining charge pump fast charging with regular fast charging. It can quickly replenish the device’s power with 30W safe supercharging, while switching to regular fast charging when near full charge. This improves charging efficiency while maintaining battery health.
5500mAh Large Battery, Durable and Long-Lasting
Using a carefully selected low-resistance fast-charging battery with high-temperature resistant materials and a low-resistance parallel MOS protection board design, the robust components ensure safety and reliability, protecting your device for extended use.

DAPS Digital Audio Purification System: Original Sampling Rate Output Across the Entire Domain
Comprising FiiO’s self-developed HiFi-grade Android multi-layer audio core and a low-jitter clock auxiliary processor, the DAPS digital audio purification system not only provides a high-precision, low-jitter unified clock source but also accurately matches various sampling rates of PCM and DSD audio. It enables original sampling rate output across the entire domain, including FiiO Music, partner music apps, and USB DACs, bringing you a purer and more authentic music experience.
Full-Range PEQ Adjustment & All-to-DSD Adjustment
The M23 supports 10-band PEQ adjustment in all operating modes. Through FiiO’s proprietary adjustment algorithm and interface, users can fine-tune the EQ frequency range, gain, bandwidth, and Q value for precise sound tuning, or simulate and correct the headphone’s frequency response curve to suit individual listening preferences. Furthermore, the M23 also supports ALL TO DSD in all operating modes, allowing users to experience the charm of different sound formats.
Six Operating Modes
The M23 features six operating modes: Roon Ready*, Android, Pure Audio, Bluetooth, and AirPlay. Users can quickly switch between various listening modes for an enjoyable listening experience. Beyond this, the M23 can receive streaming music via DLNA and play songs from NAS/LAN/cloud servers via UPNP/SMB/WebDAV.
*Roon Ready certification is underway; the specific approval time will be subject to official FiiO notification.
