FiiO M15 Portable Hi-Resolution Music Player Review
The M15 had to surpass the already excellent M11 (and the M11 Pro after that) in every conceivable way so to do that FiiO equipped it with not 1 but 2 AK4499EQ switched resistor DACs by Asahi Kasei (768KHz/32-bit/DSD512 native/140dB SNR) which they successfully paired with the Exynos 7872 hexa-core processor by Samsung (features two A73 cores clocked at 2GHz, four A53 cores clocked at 1.6GHz, 3GB LPDDR3 RAM and 64GB flash memory), the XUF208 USB chip by XMOS (768KHz/DSD512 - 384KHz/DSD128 for USB audio) and the CSR8675 v5.0 bluetooth chip by Qualcomm (supports the SBC/aptX/aptX-HD/LDAC/HWA audio codecs and features their Kalimba DSP). However, the list of hardware components is far from over since inside the M15 FiiO also managed to squeeze 7 TI op-amps (2xOPA2211/4xOPA1612/1xOPA1622), 8-layer gold PCB (complete with independent shielding and copper-nickel-zinc alloy heatsinks), ProASIC3 series FPGA (ARM Cortex-M1 processor), two custom Japanese NDK crystal units, dedicated audio capacitors and a somewhat huge 7490mAh lithium-cobalt oxide rechargeable battery (supports QC2.0/MTK PE fast charging) which can provide the M15 with up to 15 hours of music playback. An analog potentiometer volume knob, gold plated headphone outputs, left side controls and a 5.15 inch corning gorilla glass borderless screen (1440x720p/18:9/16.7 million colors/312PPI/10-finger multi-touch) complete this clearly impressive package.
