FiiO BR15 R2R — High-Resolution Bluetooth 6.0 Receiver with R2R DAC

The FiiO BR15 R2R pairs Bluetooth 6.0 wireless streaming with a fully differential 24-bit R2R resistor-ladder DAC in a single desktop unit. It accepts Bluetooth, USB, coaxial, and optical inputs and routes them through FIIO's proprietary R2R conversion stage, upgrading any amplifier, active speaker, or external DAC chain. This receiver delivers CD-quality lossless audio wirelessly while doubling as a wired DAC, preamplifier, parametric equalizer, and digital-to-digital converter.

What sets the BR15 R2R apart in its category

Most Bluetooth receivers use delta-sigma conversion, but this unit employs a FIIO proprietary fully differential 24-bit R2R architecture with 48 high-precision thin-film resistors per channel — 192 resistors total at 0.1% tolerance and 30 ppm drift. A switchable NOS/OS oversampling engine offers no oversampling for an organic presentation or upsampling to 96 kHz, 192 kHz, or 384 kHz for tighter spatial imaging.

Bluetooth 6.0 and high-resolution decoding

The wireless stage runs on Qualcomm's flagship QCC5181 chipset with a dedicated external antenna for extended range and lower latency.

• Bluetooth Version: 6.0 — LE Audio ready with up to 2.1 Mbps throughput
• Supported Codecs: LC3, SBC, AAC, aptX, aptX HD, aptX Adaptive, LDAC, aptX Lossless
• USB Decoding Max Rate: 384 kHz / 32-bit, DSD256 via XU316 controller
• Coaxial/Optical Decoding Max Rate: 192 kHz / 24-bit, DSD64

R2R conversion with balanced and single-ended outputs

The fully differential signal path runs from the R2R ladder through the LPF and volume stage, keeping noise and distortion low.

• DAC Architecture: FIIO proprietary fully differential 24-bit R2R, 192 thin-film resistors, 0.1% accuracy, 30 ppm drift
