FiiO M17

FiiO M17 - Redefined expectations for portability

Meet the M17 - FiiO's flagship DAP with qualities that are completely unheard of when it comes to portable solutions. With a DAC, amplifier and power supply that not only matches what is found in stationary amplifiers - it possibly surpasses it. The M17 redefines what is possible with portable audio players.



ES9038PRO DAC

Both the left and right channels contain 1 ES9038PRO DAC chip which is typically used in desktop setups. This means that each audio channel has 8 parallel outputs summed together for superior resolution and minimal distortion - simply an extremely clean sound production.



THX 788 headphone amplifier

When it comes to amplification, there are 2x THX 788 chips in the M17, also usually used in stationary setups. FiiO and THX collaborated to create this exclusive device, an upgrade of the original design. Compared to the original, the output power has increased by 225% with up to 3000mW per channel with a lower output impedance - this allows effortless power for all kinds of headphones.



Outstanding gain opportunities

With battery operation, you have access to 4 gain levels: low, medium high and headphone mode. With DC mode (i.e. with connected power supply) "Enhanced over-ear headphone" mode becomes available. With this mode, you get access to powers usually found in high-end stationary amplifiers. With balanced output you get +16 dB gain which allows the M17 to drive all headphones on the market.



Headphone inputs

6.3mm | 4.4mm | 3.5 mm | 2.5 mm



Connections

USB 3.0 high-speed transfer and charging

USB 2.0 for external DACs and hard drives

RCA Coaxial in/out



"Desktop-quality" Power supply

Behind the panel of the M17 you will find two power supplies - one for battery operation and one that is powered by external DC power. The battery allows you to use the M17 portable. With DC current, the voltage in the analog circuit is increased by 35%.



"Desktop-quality" heat dissipation

With exceptional sound quality you need high power consumption, with this you need good heat dissipation to prevent the components from getting too hot. Not only has "H" type heat dissipation and VC liquid cooling been used, the M17 also has an aluminum alloy frame that effectively transfers heat out of the unit. A stand with a fan is also included, which can be used in case of high consumption.



High-End op-amp

With voltage noise as low as 1.1nV@1Khz and THD+N of -136 results in an extremely clean amplification.



Flagship QCC5124 Chip

Bluetooth 5.0 support for aptX adaptive

Bluetooth receiver: SBC/AAC/aptX/aptX-LL/aptX-HD/aptX Adaptive/LDAC

Bluetooth transmission: SBC/AAC/aptX/aptX-HD/LDAC



Physical digital and analogue separation for reduced noise

Inside the M17 you have 17 different PCB boards with a gold finish. The analogue and digital circuit boards are separated to reduce the noise it would otherwise have created. 7 copper alloy shields provide additional shielding to reduce internal and external electromagnetic interference on the audio signals inside the device.



Highly optimized modular internal structure

The design of the M17 took 1.5 years to complete. With 6 major design revisions which contained 12 rounds of optimization of the internal structure. The result is that the unit makes excellent use of space.



7th generation "Mech design"

The futuristic and seamless CNC milled design evokes a feeling of a technological marvel. The "mech-inspired" sharp lines of the body, buttons and atmospheric lights give the M17 a brave and charismatic aura.



Press or twist to achieve pleasure

The volume can be adjusted either by using the analogue potentiometer or by using buttons. You can quickly and easily use 120 levels of volume in both scenarios.





XMOS receiver chip
Ultra-low delay time, supports up to DSD512 and 32bit/768kHz.

Gravity sensor
The screen rotates automatically like a smartphone thanks to a gyroscope.

Extremely fast transfer
With USB 3.0, speeds of up to 100M/S can be achieved which allow fast transfers.
