Proprietary PSRM technology
At the heart of the D900 is TOPPING's proprietary PSRM (Precision Switching Resistor Matrix) decoding system, a fully discrete 1-bit architecture that redefines digital audio playback. It consists of an ultra-fast switching logic array paired with precise voltage references, which together achieve remarkable decoding speed while preserving the purity of the original audio signal. The design emphasizes not only speed and accuracy, but also control of power supply noise. A purely resistive, noise-free reference voltage design ensures minimal distortion and noise, helping the D900 achieve harmonic distortion levels below -140 dB and a signal-to-noise ratio of up to 131 dB.
Proprietary discrete I/V conversion
Complementing PSRM decoding, the D900 features a newly developed discrete I/V converter circuit.
This stage uses carefully selected low-distortion operational amplifiers and extremely low-noise discrete components to maintain signal fidelity from digital to analog. Every component and layout detail is optimized to preserve dynamics, transient response, and sonic accuracy. As a result, the D900 delivers an exceptionally spacious and lifelike sound that sets it apart from conventional DACs.
Made for listening
Beyond its internal architecture, the D900 reflects TOPPING's deeply rooted philosophy of music-oriented design. Its clean, precise industrial aesthetic mirrors the clarity and structure of the reproduced sound. Crafted from high-quality materials with tight tolerances, the chassis underscores the product's sophistication and reliability. The minimalist exterior houses a powerful core designed not for show, but for serious listening.
Comprehensive digital compatibility
The D900 is designed to be the heart of any high-end digital audio chain. It supports a wide range of inputs, including USB-C, USB-B, coaxial, optical, AES/EBU, and I²S via HDMI, ensuring seamless integration with computers, streamers, CD players, and more. It also supports Bluetooth 5.1 with advanced codecs such as LDAC, aptX-HD, and AAC, delivering wireless performance that surpasses conventional CD quality.
True preamplifier versatility
The D900 is not only a flagship DAC, but also features a dedicated preamplifier output stage. It features high-precision volume control in 0.5 dB increments, allowing for subtle and smooth volume adjustment when used with power amplifiers or active speakers. The result is highly controlled, nuanced performance across headphone and speaker systems and the versatility to adapt to any setup.
Extremely low jitter performance
Clock precision is critical in digital audio playback. The D900 excels by using a powerful CPLD to process and refine incoming digital signals. This design dramatically reduces jitter, achieving values of up to -157 dB. This surpasses many of the most renowned DACs on the market. The result is sound that is not only clear, but also stable and extremely transparent.
Elegant and intuitive user interface
The front of the D900 features a brilliant 2-inch full-color display that clearly and elegantly displays playback information in real time. To the right of the screen, three responsive touch buttons and a precision rotary knob allow for quick, tactile control. Users can switch between different display modes—including playback information, FFT spectrum, or VU meter—and choose from nine background colors to suit their personal taste.
Premium wireless control
The D900 comes with a high-quality remote control made from a solid block of high-strength aluminum alloy. Its smooth, sandblasted finish and perfectly weighted design complement the DAC itself and enable smooth and responsive remote control. It is not only a practical accessory, but also highlights the craftsmanship of the product.
Fully customizable PEQ tuning
For users who value precise sound design, the D900 offers a new parametric ten-band EQ system. Using the desktop software, users can adjust the frequency, gain, and bandwidth of each band, import target curves, and save multiple user profiles. Whether for technical adjustments or personal preferences, the PEQ function offers powerful tools to customize the D900's output to your liking.
Flagship pairing potential
The D900 shines on its own, but when paired with the A900 headphone amplifier, it forms the basis for a truly first-class listening system. With outstanding dynamics and flawless resolution, this top-of-the-line duo takes full advantage of the highest-resolution recordings and the most sophisticated headphones—and puts you right in the middle of the music.
