FiiO S15 silver
FiiO S15 silver
With its powerful Android-based software and flagship oversampling/DAC combination from AKM, the FiiO S15 mini system delivers a smooth and detailed music experience from both integrated apps and FiiO's own Music interface. Control it via the 7.84" touchscreen or the companion app, which includes multiple operating modes. The Pure Music and USB DAC functions let you disable unnecessary processes to achieve optimal performance. HDMI ARC, along with an additional HDMI input, makes it easy to integrate into your home cinema, while a wide range of digital and analogue outputs allows for seamless incorporation into your hi-fi system. FiiO's first fully-fledged all-in-one media streamer, the S15 excels at media streaming, network streaming, LAN playback, local playback, decoding, pre-amplification and as a digital jukebox. It is equipped with top-tier components, a wide array of interfaces and numerous control options, while being fully compatible with external DACs, amplifiers and speakers.

A modern streamer designed for a premium listening experience
With its uncompromising high performance and wealth of easy-to-use music control features, it redefines the capabilities of a modern media streamer. The S15 has a standard width of 43cm, allowing it to easily match other equipment in your living room to create a unified audio system. Its 5kg all-metal body and stable anti-slip feet effectively reduce sound degradation caused by vibrations.
A clear interface with Android 12
Featuring a larger colour display than similar products and a custom version of Android 12 with a special landscape display system, the picture is clear and easy to read. Operating the device is intuitive, so you can comfortably use its various functions straight out of the box. Every touch quickly and simply takes you exactly where you need to go. The S15 uses a high-quality, low-noise custom-designed transformer to ensure power purity. The device is also equipped with four 4700µF ELNA audio capacitors, providing enough power reserve for stable and continuous operation.
Ultra-low noise and reference digital synchronisation
For the first time, FiiO uses two top-of-the-line, carefully selected ACCUSILICON AS318-B series ultra-low phase noise femtosecond oscillators (45.1584MHz and 49.1520MHz). They effectively reduce the influence of phase noise on the audio signal, resulting in high-precision decoding and digital output. When combined with high-quality external DACs and amplifiers, you can achieve reference-level sound.
Flagship AKM DAC for reference sound
Just like the Q15, K9 AKM, and M23 models, the S15 uses the acclaimed flagship AKM AK4191 + AK4499EX DAC combination. The setup is based on a new design that completely separates the digital and analogue sections and utilises 'DWA ROUTING' technology. The result is a higher signal-to-noise ratio and lower noise across different volume levels. The listening experience delivers a cleaner background, better resolution, and a natural, effortlessly relaxed sound.
Fully balanced audio design for pure sound
The S15 uses a fully balanced design from the DAC section all the way to the preamplifier. This solution significantly reduces noise and crosstalk, improving the quality of both the line and preamp outputs, with a choice between fixed and variable gain. The IV, LPF, and other audio sections use precise, low-noise OPA1612 op-amps with a high supply voltage to reproduce the dynamics of your music as faithfully as possible.
Physically separated audio sections with no interference
The digital, analogue, and power supply sections are physically separated to prevent mutual interference. This ensures signals are processed accurately and all the music's dynamics are preserved. The result is an exceptionally pure and natural sound performance. FiiO's custom PEQ algorithm and interface let you fine-tune frequency points, gain, bandwidth, and Q value. You can also correct the frequency response of headphones or simulate the characteristics of other models to suit your preferences.
Precise, low-noise power supply architecture
The design effectively prevents crosstalk between the analogue and digital audio circuits. It also provides better power isolation and greater resistance to interference. The analogue section uses a multi-stage power supply with precisely separated sections for components such as the DAC and LPF circuits. Each stage uses a series of precision low-dropout regulators (LDOs) for secondary regulation to ensure a stable, consistent, and clean power supply.
Modern horizontal FiiO OS interface
The new FiiO landscape interface is specially optimised for wide-screen displays like the one on the S15. It not only offers a clean and intuitive layout but also enhanced visual effects for an even more impressive experience. You can control it by touch, via the mobile app, or with the Bluetooth remote—whatever suits you best. A special version of the FiiO Music app, tailored to the S15's display, provides quick access to various music playback functions and settings. It also supports visual audio effects, such as VU meters, for a more engaging visual experience. Unlike other streamers, the S15 allows for extensive customisation. You can freely adjust the home screen layout to fit your own needs.
Smart control straight from your phone
FiiO places a strong emphasis on the best possible user experience. That's why the companion app features a dual-screen function, allowing you to conveniently and comprehensively control the S15 directly from your phone. The S15 supports HDMI 2.0 decoding, HDMI output, and HDMI ARC (Audio Return Channel), making it an important part of your audio-visual system. With the included Bluetooth remote, you can instantly immerse yourself in a first-class audio-visual experience. HDMI decoding/output supports sampling up to 192kHz/24-bit.
