FiiO BR15 R2R Bluetooth Receiver with Balanced XLR, LDAC & aptX Lossless

FiiO BR15 R2R is a high-resolution Bluetooth audio receiver that adds modern wireless playback to an existing stereo, powered speakers, or amplifier. Stream from your phone, tablet, or computer over Bluetooth using aptX Lossless, LDAC, and aptX Adaptive, or use it as a wired decoder with USB-C, coaxial, or optical inputs. Inside is FiiO’s proprietary fully differential 24-bit R2R DAC (quad-channel) with selectable NOS/OS modes, plus both RCA and balanced XLR line outputs. You also get optical and coaxial digital outputs for feeding an external DAC. A 1.47" colour display, IR remote, and FiiO Control app support make it easy to run from a desk or across the room.
