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 gain

Under battery power, there are 4 gain levels: low, medium, high, and headphone mode. When under DC mode, the super 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-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 analogue 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. Not only are “H” type heat dissipation and VC liquid cooling technologies adopted, the M17’s 151g unibody aluminium alloy frame also effectively transfers heat out of the device. Finally, the cooling fan stand also further makes sure heat is rapidly transported away.

Physical digital-analogue separation for reduced interference

Within the M17 and 17 PCBs with immersion gold finish, with the analogue 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 analogue audio signals within the M17.

Highly-optimised 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 optimisation. The result is a device that makes excellent use of its internal space. Within the M17 are carefully stacked analogue 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 as limited space.

Press or twist to enjoy

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