Description
The FiiO BTR17 is a portable Bluetooth DAC and headphone amplifier built for listeners who want audiophile-grade sound without giving up wireless freedom with a 240x240px screen. Three operating modes — PC, Bluetooth, and Phone — let the device adapt its power delivery to whatever source you're using, whether that's a desktop computer, a phone on the go, or a dedicated music player.
Dual ESS ES9069Q DAC chips on the fourth-generation 32-bit HyperStream architecture pair with the THX AAA 78+ four-channel fully balanced amplifier to deliver up to 650mW per channel on the 4.4mm balanced output when Desktop Mode is engaged. In portable mode, the built-in battery still provides over eight hours of playback. Qualcomm's QCC5181 chip handles Bluetooth 5.4 with LDAC, aptX Lossless, aptX Adaptive 96kHz/24-bit, aptX HD, aptX, AAC, and SBC — plus the Bluetooth LE Audio standard. Wired USB DAC playback reaches 768kHz/32-bit with native DSD512 and full MQA decoding via the XMOS 16-core XU316 chip. A 10-band high-precision lossless PEQ adjustable through the FiiO Control app or web interface lets you shape the sound to match your headphones, while a dedicated hardware shortcut button keeps tuning quick and accessible.
