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.
Features:
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 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.
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.
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.
