TOPPING raises the Bar Drawing on over 15 years of audio engineering experience, TOPPING created the D900 to deliver reference-grade sound with beautifully minimalist aesthetics. I t debuts a proprietary 32-element PSRM module and a new I/V conversion circuit—both engineered for ultra-low noise, high-fidelity playback. It also features an independent preamp circuit and versatile input options, making it a seamless fit for computers, CD players, gaming consoles, and digital transports. Proprietary PSRM Module The D900 uses a discrete 1-bit PSRM decoding architecture, minimizing power supply interference while preserving signal integrity. With nanosecond-level digital switching and a purely resistive reference power supply, it achieves harmonic distortion below –140dB and an SNR of 131dB. Proprietary I/V Conversion TOPPING’s in-house I/V circuit uses low-distortion op-amps and ultra-low noise discrete components to maintain pristine voltage output from the PSRM stage. Wireless Support with LDAC Thanks to the QCC5125 chip, the D900 supports LDAC, aptX HD, aptX Adaptive, AAC, and SBC—delivering up to 96kHz/24-bit wireless playback. Perfect for streaming from TVs, tablets, and mobile devices. Aurora UI and Remote Control A 2.0" full-color screen with a pressable knob and three control buttons offers intuitive navigation. Choose your background color and switch between FFT, VU meter, or playback info displays. The included remote, machined from a solid aluminum block, offers convenient full-feature control. 10-Band High Precision Parametric EQ Adjustment Use the desktop software to fine-tune 10 frequency bands—adjust frequency, gain, and Q-factor. Save profiles for different headphones or speakers and import/export your curves. Independent Preamp Mode Drive active speakers or power amps directly via the dedicated preamp circuit. Volume can be adjusted in 0.5dB steps via front panel or remote. Each input/output remembers its volume setting. Combine with A900 (Coming Soon) The D900 is built to complement the upcoming A900 headphone amp—offering matched design, premium specs, and a complementary aesthetic.
