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, IV, 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.

*The components are distributed under the audio shield cover.

28 high-capacity polymer tantalum capacitors

Among the M23's DAC, IN, LPF, and THX amp power sections are 28 high-capacity polymer tantalum capacitors that store large reserves of energy to be unleashed when needed - to ensure a robust power supply and ultimately powerful sound.

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.

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.

6 operating modes, 6 smooth experiences

On the M23 you can use six different operating modes: Roon Ready*, Android, Pure Music, Bluetooth, and AirPlay - all of which you can switch between quickly letting you enjoy your music the way you want. But its powerful abilities don't stop there - the M23 can also stream music over DLNA by retrieving music from NAS, local networks, and cloud servers through UPNP/SMB/WebDav.

Simply timeless, a true classic

FIIO's classic hexagonal honeycomb design with its 3D cuts and distinct edges is a bold yet attractive look. Choose between aluminum alloy and stainless steel versions, each version with its own exquisite and distinct look and feel. Whether looking at the black or blue versions, each adorned with an electroplated tempered glass panel on the back, bear witness to an intricate labyrinth where light and shadow play off of each other tastefully. The 5.5-inch high- definition display with a golden 18:9 aspect ratio both looks and feels great to use.
