Redefining portable expectations

The smart desktop-class M17 is an entirely new chapter of FiiO digital audio players. Its desktop-grade DAC, amplification, power supply, etc. give it the output power and sound quality to rival and perhaps even surpass highly-regarded desktop systems - but in a portable package. Let the M17 redefine what is possible with portable audio players.

Desktop-league DAC ES9038PRO

The left and right audio channels each contain a desktop-class, 8-channel ES9038PRO flagship DAC. This means that each audio channel has 8 parallel outputs summed together for superior resolution and minimal distortion for extremely pure audio reproduction.

140dB SNR
-122dB THD N

Desktop-class THX 788 headphone amp

Desktop-class amplification also plays an important role in the M17. FiiO and THX jointly developed the exclusive THX AAA-788 , an upgraded version of the original op-amp. Compared to the original, output power is increased by 225% up to 3000mW per channel with a lower output impedance allowing it more effortlessly power all kinds of headphones.

Output power up to 3000mW

Desktop-grade gain

Under battery power, there are 4 gain levels: low, medium, high, and headphone mode. When under DC mode, the enhanced over-ear headphone mode gain is unlocked, with a truly desktop level of amplification gain. In balanced output, gain can get as high as 16dB - allowing the M17 to easily drive most headphones.

Desktop-level connectivity

Thanks to its larger size, the M17 features a variety of connectivity options allowing for many different convenient use cases

6.35mm headphone out

4.4mm balanced headphone out/ balanced line out

2.5mm balanced headphone out

3.5mm headphone out/line out

RCA coaxial port: coaxial input and output

USB 3.0 port - Supports USB Host and Device modes, can be used for high-speed data transfers and fast charging

USB 2.0 port - Supports USB Host mode, allowing external DACs or hard drive storage to be connected

Desktop-quality power supply

The M17 contains two power supplies - a battery power supply and a power supply powered by external DC power. The battery power supply allows you to use the M17 in situations where there is no access to a power outlet. Under DC power supply, voltage in the analog circuit is increased by 35% up to 11.5V compared to under battery power supply; and the battery is kept healthy since it is not used in this mode.

Desktop-tier heat dissipation

With exceptional audio quality comes with large power consumption, so effective heat dissipation was a large focus when designing, the M17. Not only are "H" type heat dissipation and VC liquid cooling technologies adopted, the M17's 15lg unibody aluminum alloy frame also effectively transfers heat out of the device. Finally, the cooling fan stand also further makes sure heat is rapidly transported away.

Desktop-caliber internals

High-end TI OPA2211 op-amp
A voltage noise as low as 1.1nV@1KHz and THD N of -136dB results in extremely clean amplification.

470mF DMF supercapacitor
Equivalent to 10,000 47uF tantalum capacitors and with very low ESR of 45m (only 15% of that of tantalum capacitors), providing a solid foundation for a large power supply.

Ultra-low noise LT3045 LDO
An ultra-low noise, ultra-high PSRR low-dropout voltage linear regulator featuring Linear Technology's LDO architecture with an extremely low RMS noise of 0.8VRMS in the 10Hz-100kHz frequency band for stable, clean power to the DAC chip.

NDK femtosecond crystal oscillator
Provides a high-precision, low-jitter unified clock source for the entire audio circuit.

Physical digital-analog separation for reduced interference

Within the M17 are 17 PCBs with immersion gold finish, with the analog and digital sections physically separated by being on two different boards to reduce interference between the two portions. 7 high-conductivity copper alloy shields also provide shielding to greatly reduce internal and external electromagnetic interference on analog audio signals within the M17

Highly-optimized modular internal structure

The M17's design took 1.5 years to complete, going through 6 major design iterations with 12 rounds of internal structural design optimization. The result is a device that makes excellent use of its internal space. Within the M17 are carefully stacked analog and digital boards with thoughtful use of stainless-steel hexagons - which allowed FiiO to stuff nearly twice the surface area of PCBs compared to normal in such a limited space.

7th-gen mech design

The futuristic, seamless, CNC-finished aluminum unibody design evokes a sense of technological wonder. The mech-inspired sharp lines of the body, buttons, and atmospheric lights give the M17 a bold and charismatic aura.

Press or twist to enjoy

The volume can be adjusted either using an analog potentiometer knob or using buttons. Quickly and easily go through 120 levels, of volume through either method.

Radiant RGB ambient light

The M17 features a seven-color RGB ambient light system with extensive customization options. Colors can be set to be either fixed, to follow the audio, or to follow a cycle. The brightness of the ambient light can be set to change depending on the current power, volume, or temperature. And finally, the top and side ambient lights can even be controlled separately, allowing you to dial in exactly how you want your dazzling lights to be.

Bigger screen for a brighter sheen

A larger screen allows you to more easily enjoy stunning visuals. Let your eyes feast upon an upgraded 5.99-inch, 1080*2160 FHD 18:9 high-definition incell display.

Immense 9200mAh battery

The massive 9200mAh battery allows for a battery life of up to 10 hours on the M17. It can be charged either through USB or through DC in from an external DC adapter.
