A player that does it all When developing the M9, FiiO saw that there wasn't any one player that combined all of the functions people want. Was there a player that could transmit the HWA/aptX/aptX HD/LDAC lossless Bluetooth codecs, even when used as a USB DAC? What about something that also contained a highly optimized audio circuit for excellent sound quality? Did any players also give the user an experience worthy of a flagship, capable of many features including Wi-Fi music streaming all in a slick interface? We sought to change that with the M9 – which does all of this and more
Bluetooth audio unleashed with full format support The M9 uses Bluetooth 4.2 and supports virtually all Bluetooth formats including the high-resolution ones for your ultimate listening pleasure, including: 24-bit aptX HD (also backwards compatible with aptX), LDAC, and HWA. As a Bluetooth transmitter: LDAC/aptX/aptX HD/SBC (both natively from the player and through USB DAC). As a Bluetooth receiver: SBC (LDAC to be added with software updates)
10 hours playback time and 45 days deep sleep time Under normal usage the M9 can last around 10 hours, while in deep sleep (standby) mode the M9 can be still be used after a whopping 45 days! And being in deep sleep mode does not mean sacrificing convenience – just hit the power button, and the M9 instantly is ready to go.
Bring out the best in your computer with USB DAC functionality The M9 can be used as an asynchronous USB DAC with both Macs and Windows PCs. With Mac computers, you can just plug-and-play the M9 with no drivers needed. With Windows PCs, a simple install of drivers by FiiO is needed. The M9 can also act as your computer's Bluetooth transmitter – simply hook the M9 up to your computer as a USB DAC, and then have the player transmit Bluetooth audio to your headset!
USB audio and coaxial out support The M9 supports USB audio out (send digital audio bits through USB), with even support for DoP/D2P. Also, the M9 is one of the few players that can receive Bluetooth audio and output it through coaxial (SPDIF) out.
Incredibly fast with a deeply customized OS In the heart of the M9 lies the Android operating system, deeply customized by FiiO. This allows you to navigate through menus at an astonishing speed and with amazing ease due to the carefully thought out customized user interface. Also, apps for popular streaming services including NetEase Cloud Music, MOOV, Tidal and KKBOX are pre-installed to allow even more ways to listen to music. *Can install whitelisted third-party music streaming apps *Whitelisted apps: NetEase Cloud Music, MOOV, Tidal, KKBOX, Spotify, Qobuz, Roon and Deezer.
Hi-Res Audio certified The M9 has been certified by the Japan Audio Society to be “Hi-Res Audio” worthy, only achieved by devices truly capable of bringing a realistic and natural audio experience.
Dual AK4490EN DACs for superb decoding performance The two AK4490EN DACs employed in the M9 feature a high signal-to-noise ratio, exceptional dynamic range, and low distortion – making for a precise yet exciting sound signature.
Built-in dedicated FPGA with DSD128 hardware decoding Inside the M9 is a high-performance A3P030 FPGA, responsible for ensuring your music (whatever sample rate) is played back accurately by stabilizing digital clock signals. The FPGA also decodes DSD64/128 in hardware, which the M9 supports in ISO/DFF/DSF formats.
Eight-layer HDI PCB ensures excellent sound quality For the first time, in the M9 FiiO uses an eight-layer HDI (High Density Interconnect) PCB with a thickness of only 0.08mm. While the M9 PCB is more complex than the one in the M7, it also allows more components to be integrated into a smaller space, leading to a smaller PCB and a smaller device overall. Combined with the fact that the M9 PCB is L-shaped, similar to modern smartphones, and you have a recipe for outstanding sound quality.
Specially-designed audio circuit with balanced and single-ended outputs The TI OPA1612 is used as the LPF, while the TI OPA1622 serves as the current buffer. To achieve single-ended and balanced output, there are two OPA1622 op-amps used that provide up to 77mW* of power under a 300Ω load.
