Flagship DAC Combo

The FiiO M23 utilizes the flagship AKM DAC combo, the AK4191EQ and AK4499EX DACs. 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.

8-Way Parallel Amplification

Refining the AAA 78 amps found in the M11 Plus and Pro, FiiO equips the M23 with dual 4-way fully balanced THX AAA 78+ amps. They combine for true, balanced 8-way parallel amplification with greater power output while maintaining high fidelity music.

High-Caliber Audio Architecture

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.

4-Stage 20-Rail Power

In order to handle all of this advanced analog and digital internal circuitry, FiiO gave the M23 a robust 4-stage 20-rail power supply. The system is comprised of independent digital and analog power supplies. The analog supply has separate rails for the DAC, small and large amplification parts, four stages of power processing: OVP, adaptive and LDOO voltage stabilization, high-efficiency voltage boosting, and Pi filtering.

A total of 28 high-capacity polymer tantalum capacitors are used to store large amounts of reserve energy when needed, with the primary analog power supply getting 4 KEMET low ESR high ripple suppression polymer tantalum capacitors, the THX power supply getting 12 KEMET capacitors, the I/V & LPF power supplies getting 6 AVX capacitors, and the DAC receiving 6 KEMET capacitors.

Additional Features

Dual-Mode Fast Charging
To help deliver the fastest charging times while maintaining battery health, the M23 can utilize extreme fast charging of up to 30W at a lower battery level, and auto-switch to a slightly slower normal fast charging mode when the battery is closer to being full.

Patented Desktop Mode
When desktop mode is activated, the M23 is completely powered by an external power source. The M23 can be used as desktop equipment without fear of damaging the battery.

8 Panasonic Film Capacitors
In the LPF section, 8 Panasonic film capacitors are used to give the M23 the ability to produce stable and consistent sound at each frequency band from both the left and right channels.

Large 5500mAh Battery
Specially selected low-resistance fast-charging batteries that employ high-temperature resistant material are paired with a low resistance MOS protection board to ensure the batteries will last a long time.

Digital Audio Purification System
The DAPS (Digital Audio Purification System) as featured on the M23 consists of both the FiiO HiFi audio core that bypasses the original Android version plus a low-jitter clock compressor.

Global PEQ and All-To-DSD
A 10-band PEQ can be used in any operating mode to adjust EQ frequency points, gain, bandwidth, and Q value. This lets users fine tune or correct headphone frequency to their personal preferences, and All-to-DSD can be activated to experience audio in different formats.

6 Operating Modes
Enjoy your music the way you want with six different operating modes: Roon Ready, Android, Pure Music, Bluetooth, AirPlay, or over DLNA from a NAS, over a local network, or cloud servers through UPNP, SMB, or WebDav.
