FIIO M9 High-Resolution Digital Audio Player: Compact Music Player DAP (M 9, M09)
FiiO M9
The Ultimate in Versatility
Portable High-Resolution Audio Player
A player that does it all
When developing the M9, we at 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: Functionality to be added with software updates
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.
Get your music from wherever and whenever
With the M9, you can get your music from wherever, whenever. Don't want to deal with wires when transferring your songs over? Use Wi-Fi on the M9. Want to listen to your music on your computer? Do so with DLNA without having to worry about space on the M9. Want to discover new music on streaming services? The built-in streaming apps have you covered.
*Can install whitelisted third-party music streaming apps
