FiiO M15 Hi-Res Music Player

Dual AK4499EQ DAC

The AK4499EQ is the flagship of the 3rd generation DAC AKM. With 4 channels per chip, an improved architecture and the use of the LSI manufacturing process, these chips offer incredible performance. The DAC is capable of decoding sample rates up to 32bit 768kHz and DSD512 and offers a signal-to-noise ratio of 140dB and a THD+N of -124dB.

XMOS XUF208 USB Interface

When used in USB DAC mode, the M15 takes advantage of the performance of its XMOS XUF208 USB interface. This contributes to the quality of DAP playback and also supports sample rates up to 32bit 768kHz and DSD512.

Qualcomm CSR8675 Bluetooth Receiver/Transmitter

The M15’s Bluetooth receiver chip, a Qualcomm CSR8675, the manufacturer’s premium model, enables high-quality Bluetooth transmission. It enables stable and fast broadcasting, including support for the aptX, aptX, LDAC and HWA codecs for superior listening quality.

Exynos 7872 CPU

Navigation within the M15 interface is perfectly fluid, using an Exynos 7872 processor. This one integrates 2 A73 cores and 4 A53 cores. 3GB of RAM are associated with it with also 64GB of storage and the possibility to add a Micro SD card (up to 2TB). The M15 also allows dual band 2.4/5GHz WiFi transmission.

Femtosecond NDK Crystals

The M15 incorporates two custom NDK femtosecond oscillators, ensuring a phase noise of only -140dBc/Hz @ 1kHz offset. These oscillators are coupled with a 3rd generation FPGA to further lower the jitter and provide the DAC with the most accurate clock signal.
