Topping Centaurus R2R Desktop DAC

TOPPING collaborates with HOLO AUDIO to launch a brand new fully balanced 8-channel R2R DAC.

TOPPING X HOLO AUDIO
It features 8 resistor array networks, distributed across both sides of the circuit board, creating a unique fully balanced configuration. Four resistor arrays on the front side are dedicated to DSD decoding, employing what is termed a "Vector Step Resistance Network," while the other four arrays on the reverse side handle PCM decoding, utilizing the classic R2R structure. The high-performance decoding unit, powered by an CPLD, ensures exceptional sound fidelity and precise audio reproduction.

NOS/OS/Best Three-Mode Switching
OS Mode: Applies oversampling to digital signals to minimize quantization errors, reduce noise, and improve the SNR and DNR, significantly enhancing audio performance. You can manually select different oversampling rates within the OS mode to achieve a sound quality that aligns with your preferences.

NOS Mode: Bypasses oversampling and decodes audio at the original sample rate, preserving the authentic characteristics of the audio signal for the most accurate and real listening experience.

Best Mode: Automatically selects the optimal oversampling rate based on the source's sample rate and the DAC's internal processing capabilities, achieving an ideal balance between performance and sound quality.

Ten bands high-precision PEQ adjustment
We developed a brand new PEQ adjustment* that supports ten customizable frequency bands. TOPPING's brand new PEQ algorithm and desktop software allow you to fine-tune the frequency, gain, and bandwidth of each PEQ band. The software supports the import of target curves and raw curves, and enables curve compensation using the target curve. It can also save multiple profiles for easy switching.

LDAC wireless available
Equipped with QCC5125 chip, TOPPING Centaurus supports Bluetooth 5.1 and can support up to 96kHz/24bit. Also it fully supports LDAC/aptX-Adaptive/aptX/aptX HD/AAC/SBC and other audio encodings, allowing high-quality audio to be transmitted wirelessly to provide a music experience beyond CD level.

Plug and play
TOPPING Centaurus has a wide range of compatibility and apply to various operating systems such as Windows 10, Windows 11, MAC, Linux and iOS/Android. The USB hardware is based on third generation XMOS XU316 and Thesycon driver*. It's stable and reliable. In addition, the USB input supports up to PCM768kHz/32bit and DSD512, which makes every detail vivid.

*Note: Only for Windows ASIO applications, you need to install the Thesycon driver and set it up. Driver is not required under other systems.

Self-developed IV circuitry unlocks full DAC potential
Our self-developed I/V conversion module is dedicated to achieving superior audio reproduction. The exceptional circuit design delivers lower distortion and noise while occupying less space. Designed to approach physical limits, it pushes the performance of R2R DAC to the extreme.

Realistic reproduction
TOPPING Centaurus has exceptional music reproduction capabilities among R2R devices, with THD+N < 0.0005%. It faithfully reproduces every note captured in the original recording, rendering even the finest details of the music. Even if you are not at the live concert or recording, you can experience the vivid sensation of being right there, with every nuance presented delicately and naturally.

Choose your output mode at will
TOPPING Centaurus has universal RCA single-ended outputs and professional XLR balanced outputs. You can turn on only the output channels you need, or output both channels at the same time. Whether you are connecting two different systems or need to output two audio signals at the same time, TOPPING Centaurus can provide you with a more convenient and efficient output method.

In addition to the more universal XLR 4V and RCA 2V outputs, TOPPING Centaurus also adds XLR 5V and RCA 2.5V When XLR 4V and RCA 2V are selected, more devices can be adapted. When XLR 5V and RCA 2.5V are selected, the performance will be pushed from extreme to more extreme.

IIS - Ultra-high specification signal input interface
IIS interface is not HDMI, but a customized digital audio transmission interface, which supports up to PCM768kHz/32bit&DSD512native. DAC IIS needs to match the IIS interface definition of the digital interface. TOPPING Centaurus supports many IIS interfaces*. It is also compatible with most digital interfaces.

Directly connect active speaker to adjust volume
In addition to the fixed output level DAC mode, TOPPING Centaurus also has a "preamp" mode. In preamp mode, you can adjust the output volume of TOPPING Centaurus, then connect it directly to a pure amplifier or active speaker, that saves the cost of a pre-amplifier. You can also use the TOPPING Centaurus remote control to control the volume, which is further convenient for use.
