The Topping D900 is more than just a DAC – it is the pinnacle of TOPPING’s engineering, designed to deliver reference-grade sound reproduction for the most discerning audiophiles. Featuring the brand-new self-developed PSRM discrete 1-bit DAC architecture, the D900 pushes digital-to-analog conversion into new territory with unprecedented clarity, precision, and musicality.
Every detail in the D900 has been purpose-built to maximize performance. Its 131 dB SNR and ultra-low THD+N of <0.000055% guarantee a transparent listening experience that reveals every nuance in your recordings. Combined with ultra-low jitter clocking (–157 dB), the D900 achieves flawless timing and holographic sound staging.
A fully modern user experience comes via the Aurora UI, a vibrant 2-inch color display that allows you to toggle between playback data, FFT spectrum analysis, or classic VU meters. With customizable themes, tactile button controls, and remote functionality, the D900 seamlessly blends audiophile performance with modern convenience.
For system integration, the D900 offers a dedicated preamp mode with independent circuitry, giving you precise 0.5 dB volume control whether you’re running powered monitors, integrated amps, or headphones through an external amplifier. Its 10-band parametric EQ (PEQ) software allows you to finely shape your sound, with the ability to save, import, or export EQ profiles tailored to your preferences.
With support for Bluetooth 5.x streaming featuring LDAC, aptX HD, and aptX Adaptive, the D900 ensures your wireless listening matches the fidelity of its wired performance. Add in its wide array of inputs (USB, optical, coaxial, AES, IIS, Bluetooth) and balanced XLR outputs, and you have a DAC designed to be the centerpiece of any high-end audio system.
The Topping D900 is not just a component – it is the cornerstone of an uncompromising desktop or home audio setup.
