<FiiO> BR15 R2R — A New Frontier in Desktop Wireless HiFi with Proprietary R2R DAC and Bluetooth 6.0
Hello, this is Ryo.
Thank you for reading this article!
FiiO is introducing the "BR15 R2R", a desktop audio receiver that combines a proprietary full-balanced 24-bit R2R DAC with Bluetooth 6.0.
It is a multifunctional device that achieves CD-quality wireless playback with aptX Lossless support, while also functioning as a USB DAC and offering digital input/output. I will be introducing this device, which is capturing the attention of audiophiles.
FiiO BR15 R2R
BR15 R2R is a desktop Bluetooth audio receiver and USB DAC equipped with a 4-channel full-balanced 24-bit R2R DAC independently developed by FiiO. Its main feature is the discrete R2R circuit, composed of 192 high-precision thin-film resistors (0.1% precision, 30ppm temperature drift) in total, with 48 per channel. You can expect a warm, analog-like sound that differs from the delta-sigma method.
It is equipped with the Qualcomm QCC5181 flagship chip with Bluetooth 6.0 support, offering broad compatibility with major high-quality codecs such as aptX Lossless, LDAC, and aptX Adaptive. Analog outputs include two sets of RCA and one set of XLR balanced outputs, providing flexibility for connections to active speakers or power amplifiers. The 1.47-inch custom color LCD displays song titles, artist names, and even lyrics.

🟢 Comparison between BR15 R2R and 🔷 K11 R2R
BR15 R2Rand K11 R2R are both desktop units equipped with FiiO's proprietary discrete R2R DAC. The biggest difference lies in their intended use; the BR15 R2R
is designed as a wireless receiver and line-output device supporting Bluetooth 6.0 and aptX Lossless. On the other hand, the K11 R2R features a built-in headphone amplifier (up to 1,300mW output), making it a great choice for earphone and headphone users. The BR15 R2R has advantages such as XLR balanced output, a color LCD, and a remote control, but it lacks a headphone output. Choosing the right one depends on how you plan to use it.

Recommended Points
✅ Warm sound of the proprietary R2R DAC
A full-balanced 24-bit R2R DAC composed of 192 high-precision thin-film resistors. It offers an analog-like tone that differs from the delta-sigma method, making it an irresistible choice for those who feel something is missing from the "coldness" of digital audio sources.
✅ Bluetooth 6.0 + aptX Lossless support
With Bluetooth 6.0 powered by the QCC5181 flagship chip, it covers major high-quality codecs such as aptX Lossless and LDAC. You can enjoy CD-quality playback while making your existing speakers or amplifiers wireless.
✅ Versatile hub with diverse inputs and outputs
In addition to four input systems—Bluetooth, USB, optical, and coaxial—it is equipped with two RCA analog outputs, an XLR balanced output, and optical/coaxial digital outputs. You can consolidate various sources like smartphones, PCs, CD players, and TVs into one unit.
✅ Two sound signatures with NOS/OS mode switching
In Non-Oversampling (NOS) mode, you can enjoy organic and natural sound, while in Oversampling (OS) mode, you can enjoy clear sound upsampled to a maximum of 384kHz. It seems fun to be able to switch according to your mood or the source.
✅ 10-band PEQ + AUTO EQ
Equipped with a 10-band parametric EQ applicable to all modes. It supports everything from preset selection to exporting and importing custom curves, and the AUTO EQ function allows for automatic correction by specifying headphone data and target curves.
✅ Color LCD even displays lyrics
The 1.47-inch custom color LCD displays song titles, artists, sampling rates, and EQ information, and even shows lyrics during Bluetooth playback. It is sure to enhance the sense of ownership when placed on your desk.
✅ Comfortable operation with remote control + app
You can operate it from a distance using the included infrared remote control and the FiiO Control app. It is perfect for setups where you place it in the living room and control it from the sofa.
Recommended for people like this
Those who want to add Bluetooth functionality to existing speakers or amplifiers
Those interested in the warm sound of an R2R DAC
Those who want to enjoy high-quality wireless playback with aptX Lossless
Those who want to consolidate multiple digital sources (PC, CD, TV, etc.) into one unit
Those who want a DAC/preamp that can serve as the core of a living room audio system
Those who feel that digital sound sources lack warmth
Those who want to carefully fine-tune parametric EQ on a desktop DAC
However, it does not have a headphone output. If you mainly want to use earphones or headphones, please consider the K11 R2R, which is equipped with the same R2R DAC, or adding a separate headphone amplifier.
