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.
