Desktop-level connectivity

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

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.

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.

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.

Coaxial decoding

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.

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.

A first-rate premium experience

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.

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.

With exceptional audio quality comes 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 151g 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-tier heat dissipation

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-quality power supply

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.
