Full Description
View Full DescriptionDual AKM DAC Chips
The FiiO M23 features the flagship AKM DAC combination, AK4191EQ and AK4499EX, which innovatively separates digital and analogue signals. Enhanced with DWA ROUTING technology, this architecture significantly improves the signal-to-noise ratio, providing a cleaner audio background and minimising unwanted interference for a more natural listening experience.
THX AAA 78+ Amplification
Featuring THX AAA 78+ amplifier architecture, the FiiO M23 delivers enhanced power output with minimal distortion. This four-way fully balanced design has been continuously improved based on feedback of previous models like the M11 Plus and M11 Pro. It ensures improved channel separation and reliable power output, perfect for driving both sensitive and high-impedance headphones.
Dual-mode Safe Charging
The FiiO M23 features a dual-mode fast charging system that utilizes both extreme and normal fast charging. This allows the device to adjust charging speeds based on the battery's current level, ensuring up to 30W of safe charging. It's designed to efficiently manage battery health and reduce charging times, extending the battery health and life on the go.
Six Versatile Listening Modes
The FiiO M23 features six operating modes: Roon Ready*, Android, Pure Music, Bluetooth, AirPlay, and DLNA streaming. These modes enable seamless switching to match your listening preferences and support streaming from various sources, including cloud servers, local networks, and third-party apps.
*Roon Ready certification is currently in progressRobust Build Quality
Equipped with a 10-band Parametric Equaliser (PEQ), the FiiO M23 allows users to finely adjust frequency, gain, and bandwidth across all modes. It also supports high-resolution audio up to 384kHz/32-bit PCM and DSD256, preserving original sampling rates for truly authentic sound quality.
Desktop Mode
