FiiO M17 Portable Desktop-Class Music Player

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. 

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. 

Desktop-Grade Grain

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 the balanced output, the 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.

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, the 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 large power consumption, so effective heat dissipation was a large focus when designing the M17. Finally, the cooling fan stand also further makes sure heat is rapidly transported away. 

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 Ml 7 a bold and charismatic aura.
