FiiO M15 Flagship Android Lossless Player

No nonsense, all high performance dual AK4499EQ flagship DACs

The AK4499EQ is AKM’s flagship third generation DAC. With four channels per DAC chip, a current output architecture, and being manufactured on the LSI special process, the AK4499 has impressive performance. The DAC chip is capable of decoding up to 768kHz sampling rate and native DSD512, and has a signal-to-noise ratio up to 140dB and THD+N as low as -124dB.

XMOS XUF208 USB chip support up to 768kHz/32bit, DSD512

When in USB DAC mode, the M15 utilizes professional grade XMOS XUF208 USB chip, supporting up to 768kHz/32 bit and DSD512 input.

Qualcomm CSR8675 Bluetooth chip supports two-way LDAC lossless Bluetooth

When the M15 is used as a Bluetooth receiver, Qualcomm’s CSR8675 flagship Bluetooth chip comes into play for complete Bluetooth audio format support as well as enabling lower latency and faster transfer speeds.

Exynos 7872 processor - Unrivalled processing power

• Dual A73 Cores + Quad A53 Cores
• 3GB RAM + 64GB Storage + 2TB Expansion
• Supports 2.4/5GHz dual-band WiFi

NDK femtosecond crystal

The two custom Japanese NDK femtosecond crystals in the M15 allow for a phase noise as low as -140dBc/Hz @ 1kHz offset. These crystals work in conjunction with the 3^rd gen FPGA clock algorithm, for lower jitter and ultimately a more accurate clock for the DAC.

FiiO 3rd gen FPGA

Present in the M15 is FiiO’s self-developed 3^rd generation FGPA with more advanced algorithms, more accurate clocks, and even further reduced jitter.

Parts worthy of a flagship

• Ultra-low noise resistors - high precision 0.1% tolerance, low temperature drift, low noise film resistors
• Dedicated audio capacitors - 4 low-loss polymer tantalum capacitors + 4 Panasonic electrodeless film capacitors + 8 small film capacitors
• Ample power reserves - 28 220uF low-loss polymer capacitors, 5 100uF high-voltage capacitors
• Impressive LPF configuration - Eight 4-way independent Panasonic metallized film capacitors

Sharply dressed and well-equipped inside and out

The M15 adopts a fully balanced architecture to ensure every last detail can be heard without sacrificing bold dynamics. Inside this balanced architecture are: 2 all-new high-precision, low-noise, low temperature drift TI OPA2211 op-amps for the low-pass filter, 4 OPA1612 for IV conversion, and 1 OPA1622 for amplification of each channel.

Technologically rivals the best smartphones

• 8-layer ultra-thick immersion gold PCB Greatly improves space utilization, and ensures no interference between digital and analog circuits
• Independent shielding for digital and analog circuits + special absorbant material for further improved shielding against interference, and pro-grade material specifically to absorb 2.4GHz waves further helps
• Customized thermally conductive silicone, graphene, and copper-nickel-zinc alloy heatsinks effectively conducts internally-generated heat to the outer body, which allows the heat to dissipate into the air

Handle it all with active servo power technology

For the first time, FiiO has implemented “active servo power” technology to the final amplification stage, which allows the power output to change depending on the user’s preferred settings. When paired with IEMS, you can set the M15 to be optimized for minimal noise as possible. But if you want to use your hard-to-drive 300 ohm headphones, you can enable Big Driver mode to turn your M15 into a power monster capable of pushing such headphones to their limits.

Monstrous power output comparable to desktop amps

Under a 32-ohm load, single-ended output power is 490mW and balanced output power up to 800mW. Under a 300-ohm load, single-ended output power is 70mW and balanced output power up to 275mW.

A quiet listening background as black as the universe

• Noise floor as low as 2.1μV
• Distortion as low as 0.0004%
• S/N Ratio up to 122dB

15 hours battery life, 1800 hours standby time

• 7490mAh high energy density lithium cobalt oxide battery
• Custom FPC and Japanese SMK battery connector
• Supports QC2.0, MTK PE, and USB PD fast charging

5th gen classic columnar design with arched design for a comfortable grip

The M15 represents the 5^th generation of the basic classic columnar design that defined FiiO’s previous models, such as the Q1 Mark II/K3/K5 Pro. The left and right sides are made concave to facilitate gripping the device, and the overall arced design gives the M15 totally unified design.

Analog potentiometer volume knob for pro-grade audio adjustment

ADC curve reconstruction as employed in the M15’s volume adjustment solves problem traditionally associated with analog potentiometers, such as volume imbalance between the left and right channels.
