The Ultimate Digital Transport: FiiO S15 High-Res Audio Streamer

Welcome to the new brain of your audio system. The FiiO S15 is a flagship-tier desktop streamer, DAC, and preamplifier engineered to bridge the gap between cutting-edge network technology and uncompromising traditional HiFi. Housed in a premium, full-width (43cm) metal chassis designed to sit perfectly in your equipment rack, the S15 delivers state-of-the-art decoding and unmatched versatility for the modern audiophile.

Why the FiiO S15 Stands Alone

• Flagship AKM DAC Architecture: At its core, the S15 boasts a fully separated digital and analog signal path powered by the flagship AK4191EQ and AK4499EX DAC combo. Combined with dual Accusilicon AS318-B femtosecond crystal oscillators, it delivers ultra-low jitter, breathtaking clarity, and an incredibly organic, dynamic sound signature.

• A Visual Masterpiece: Navigate your entire music library with ease. The front panel is dominated by a stunning 7.84-inch automotive-grade color touchscreen. Running a highly customized, landscape-oriented Android 12 OS powered by a Snapdragon 660 processor, the S15 gives you native access to all your favorite streaming apps, complete with customizable VU meters and a beautiful UI.

• Audiophile-Grade Power Supply: Clean audio starts with clean power. The S15 utilizes a custom low-noise 35W linear power supply featuring a toroidal transformer and four massive 4700uF ELNA capacitors. The digital and analog sections are powered independently to eliminate cross-interference and ensure a pitch-black background.

• Limitless Connectivity: Whether you are building a modern digital stack or integrating into a home theater, the S15 has you covered. It features standard outputs like balanced XLR and dual RCA, but goes above and beyond with AES/EBU, I2S, HDMI, and HDMI eARC connections. (Note: As a dedicated source component, the S15 does not include a headphone output).

• Massive Local Storage: Have a massive local library? Connect external drives via USB, pop in an SD card, or utilize the rear-panel M.2 NVMe SSD hard disk cage (supporting up to 2TB) to build a lightning-fast, fully self-contained digital jukebox.

Unrestricted Streaming

The S15 doesn't lock you into a single ecosystem. It is fully certified Roon Ready, and supports Apple AirPlay, DLNA, and native apps for Tidal, Qobuz, Spotify, and more.

If you prefer to stream directly from your phone or tablet, the integrated Qualcomm QCC5125 Bluetooth 5.1 chip provides rock-solid, high-resolution wireless reception via LDAC and aptX Adaptive.
