FIIO S15 Streamer Preamplifier DAC Black

With its S15, FiiO unveils a very high-quality audio streamer. In fact, it rivals many high-end streamers for a price that defies all competition. Ultra-complete, this device offers numerous streaming solutions thanks to its Android 12 operating system, while relying on a combo of AK4191EQ + AK4499EX DAC chips for top-level audio performance. It supports sampling rates up to PCM 32bit 768kHz and DSD512. It can also act as a preamplifier on its RCA and XLR line outputs. Thanks to its attractive color touch screen and operating system, it provides access to various streaming services such as Qobuz, Tidal, Amazon Music and Spotify.

It also features Bluetooth 5.1 with a Qualcomm QCC5125 chip and compatibility with DNLA, Airplay and Roon protocols. In terms of connectivity, it's not to be outdone, with a USB-C input, an HDMI input, TOSLINK optical and SPDIF coaxial input/outputs, as well as RCA and XLR line outputs.

FiiO S15: A linear power supply

The FiiO S15 streamer features an ultra-low-noise 35W linear power supply to power all its audiophile components. This power supply is furthermore coupled with four Elna 4700µF capacitors to ensure high current capacity. It's also worth noting that each stage of the network player is isolated for protection against interference and improved dynamics for clear, pure sound reproduction.

FiiO S15: Fully balanced analog architecture

The analog circuitry of the FiiO S15 benefits from a fully balanced architecture from the DAC to the preamplifier stage. This considerably reduces noise and delivers a pure signal to the streamer's outputs. The outputs also feature both fixed and variable levels, allowing the S15 to be used as a preamplifier. In fact, the analog output stage is based on OPA1612, ensuring high voltage levels and good dynamics.

FiiO S15: a large color touch screen

The FiiO S15 features a large color touchscreen on its front panel. The Android 12 interface can be accessed via this for easy access to the various services. In addition, numerous interfaces are available, such as a vumeter, and the home screen is customizable.

FiiO S15: 10-band equalization

A proprietary algorithm and interface provide the FiiO S15 with 10-band equalization, including gain, frequency, bandwidth and more. This function is available for all S15 operating modes, and can even simulate a specific frequency response.
