Interacting with the device directly is intuitive, so that it is easy to handle various operations right out of the box. You can directly feel how each touch gets you easily and quickly to where you want.

Cutting-edge masterpiece A window into the future

Everything is covered,A true audio “master”

Streaming media: Android 12 + a custom landscape display system means you can freely install many apps and smoothly use them. Network streaming: With it being Roon Ready and AirPlay, and capable of DLNA streaming and Bluetooth reception, you can enjoy high-quality streaming music.

LAN playback: Play music from your NAS/LAN/cloud servers through network protocols including UPNP/SMB/WebDAV.

Local playback: Besides locally stored music, you can also play files from microSD cards, USB flash drives, portable hard disks, and other devices.

Precisely restored audio,Every last detail present

For the first time, FIIO utilizes two industry-leading ACCUSILICON AS318-B series ultra-low phase noise femtosecond oscillators (45.1584MHz, 49.1520MHz), which have been fully screened. These effectively reduce the impact of phase noise on audio signals, resulting in high levels of decoding fidelity and digital output precision. When paired with high-performance external decoders and amplifiers, you can achieve reference-grade sound.

No resampling throughout

FIIO’s proprietary (DAPS digital audio purification system), composed of a custom Android audio core and a low-jitter clock coprocessor, has been refined over many years. It allows for non-resampled audio globally at both the application and system levels. It can also accurately match various sampling rates of PCM and DSD audio for purer music.

Digital-analog separation Exactly reproducing the original sound

AKM flagship DAC combo AK4191+AK4499EX 

Like in the Q15, K9 AKM, and M23, the S15 also utilizes the highly acclaimed AKM flagship DAC combo - AK4191+AK4499EX. This combo is based on a new design that fully separates the digital and analog portions and also incorporates ‘DWA ROUTING Technology’ – all of which enhances signal-to-noise ratio and reduces noise across various amplitudes. The audible result is a cleaner background and improved resolution to deliver a natural, relaxed, and totally unstrained sound.

Fully balanced analog audio architecture

The S15 uses a fully balanced design, including everything from the DAC decoding to the preamplifier stage. Such a design significantly reduces noise and crosstalk and improves the line and preamp output quality – for which you can choose between fixed or variable gain. The IV, LPF, and other audio sections count on OPA1612 low-noise precision op-amps for high voltage supply to ensure the dynamics in your music are faithfully reproduced.

Premium materials All in the quest for sound quality

Physical partitions and shielding Enjoy “pure” heavenly sound

The digital, analog, and power sections are physically separated to prevent mutual interference, which ensures signals are accurately processed and all dynamics within the music are preserved. The end result is that you get to enjoy “pure” heavenly sound.

Precise power supply design

Separated digital and analog power supplies

This design effectively prevents crosstalk between the analog and digital audio circuits. It also provides better power isolation and interference resistance.

Multi-stage analog power supply

The analog section is powered by a multi-stage power supply, with precisely divided stages for components like the DAC and LPF. Each stage employs numerous precision low-dropout regulators (LDOs) for secondary regulation to ensure a consistent, stable and pure power supply.
