Utilises Discrete 1-Bit Decoder Architecture For High-Resolution Audio Output

Topping D900 features a self-developed PSRM module, a discrete 1-bit decoding architecture built with an ultra-high-speed switching logic array and precision voltage references. After evaluating over 20 configurations, the selected components offers extremely fast response while preserving the integrity of the original signal. This careful selection also minimises interference with the power supply system, creating a solid foundation for exceptional audio performance.

Embeds Precision Voltage Reference For Ultra-Low Distortion

Topping D900 features a noise-free, purely resistive voltage reference power design that ensures exceptional analog output accuracy. It is combined with nanosecond-level digital switching logic that enables to achieve ultra-low distortion below -140 dB and a signal-to-noise ratio of 131 dB.

Fused With All-New I/V Conversion Circuit For Excellent Dynamic Range

Topping D900 introduces a newly designed I/V conversion circuit aimed at superior audio reproduction. The proprietary circuit utilises low-distortion operational amplifiers and ultra-low-noise discrete components, meticulously selected through repeated testing. This ensures that the PSRM’s voltage output remains untainted, delivering dynamic range and immersive sound quality.

Features CPLD For Ultra-Low Jitter & Uncompromised Sound Quality

Topping D900 achieves ultra-low jitter through the use of CPLD (Complex Programmable Logic Device) to process and optimise the digital clock signal. In widely recognised jitter measurement tests, the D900 performs exceptionally well, achieving jitter rejection as low as -157 dB, demonstrating its commitment to uncompromised digital signal accuracy.

Tailor Your Music With The 10-Band High-Precision PEQ Adjustment Feature

Topping D900 includes a brand-new 10-band high-precision PEQ adjustment feature. This advanced system allows for fine control over frequency, gain, and bandwidth for each band via Topping's custom desktop software. Users can import target and original curves, apply curve compensation, and save multiple profiles for seamless switching, ideal for tuning to personal preferences or professional needs.

Connect Wired & Wirelessly For Seamless Compatibility Across Devices

Topping D900 is equipped with an extensive selection of digital inputs- USB-C, USB-B, optical, coaxial, Bluetooth, AES, or IIS-LVDS to effortlessly integrates with computers, CD players, digital transports, and gaming consoles, unlocking their full sonic potential. It supports high-resolution wireless audio through the integration of the QCC5125 Bluetooth chip. With support for Bluetooth 5.1 and high-definition codecs such as LDAC, aptX Adaptive, aptX HD, and AAC, it allows streaming at up to 96kHz/24bit—delivering wireless audio performance that exceeds CD quality.

Features Dedicated Preamplifier For Refined Volume Control

Topping D900 includes a dedicated preamplifier circuit, extending its versatility for use with floorstanding speaker systems. Its precision volume control, adjustable in ultra-fine 0.5 dB steps, allows for refined loudness adjustments that ensure a smooth and comfortable listening experience.

Embeds HD Display Screen & Touch buttons With A Multifunction Knob

Topping D900 features a 2-inch full-color display that provides clear real-time playback information. Three responsive touch buttons alongside a multifunction volume knob offer fast, intuitive control. The knob not only adjusts volume with precision but can also be customised to suit personal usage preferences. Users can switch between multiple display modes including playback info, FFT spectrum, or VU meter and choose from 9 background colours for a personalised visual experience.

Meticulously Crafted With Bold Design & Minimalist Aesthetics

Topping D900 is defined by its clean, angular design, an aesthetic rooted in both structure and emotion. Like a well-composed musical arrangement, the form strikes a balance between order and expression. Beneath its minimalist exterior lies a highly refined sound signature, embodying the D900’s dual nature: bold design and audiophile-grade performance. It includes a premium remote, CNC-machined from high-strength aluminium and sandblasted for a refined, tactile finish.
