The FiiO BR15 R2R is an elegantly designed desktop Bluetooth receiver that combines wireless freedom with audiophile sound quality. At its core is a fully balanced 24-bit R2R DAC with four differential channels and a total of 192 high-precision resistors. This R2R architecture delivers strikingly nuanced and structured sound reproduction. Users can choose between a no-oversampling mode for faithful signal reproduction and an oversampling mode of up to 384 kHz, which highlights the finest details even more precisely. With the integration of the Qualcomm QCC5181, Bluetooth 6.0 is supported, including aptX Lossless, aptX Adaptive, and LDAC, ensuring wireless transmission in CD quality. Versatile connectivity is enhanced by USB, optical, and coaxial digital inputs, as well as analog outputs via RCA and XLR. Digital outputs are also available. For precise sound tuning, a globally applicable 10-band PEQ is available, which can be controlled via an app and also allows for automatic frequency response correction through AUTO EQ. The fully balanced signal path from the DAC to the volume control minimizes distortion and maximizes dynamic range. An integrated AC power supply ensures stable power delivery. Optionally, an external 5V DC supply can be connected to further optimize sound performance. The 1.47-inch display provides all relevant information at a glance. The BR15 R2R is aimed at discerning listeners who want to combine state-of-the-art wireless technologies with uncompromising signal processing and high-quality features. With its thoughtful architecture and detail-oriented sound signature, it sets new standards in the realm of wireless HiFi components. This device is the ideal solution for anyone looking to experience wireless high-end audio at the highest level.
