Utilises Self-Developed PSRM Architecture For Exceptional Audio Quality

Topping DX9 Discrete features a self-developed 16-element PSRM module for left and right channels. PSRM is a fully discrete 1-bit decoding architecture built from an ultra-fast switching logic array and high-precision voltage references. Each component is curated from over 20 specialised part types to achieve nanosecond-level response, exceptional signal integrity, and reduced power interference. This results in a stable, low-noise foundation that enhances detail retrieval and dynamic accuracy.

Features Six-Channel Discrete NFCA Headphone Amplifier For Seamless Pairing

Topping DX9 Discrete employs a flagship-grade six-channel NFCA amplifier, with independent circuits for single-ended and balanced outputs. Noise levels remain extraordinarily low at

Embedded With High-Precision Voltage Reference For Analog Accuracy

Topping DX9 Discrete uses a pure resistive output supply to stabilise the voltage reference system. While the digital switching logic operates at nanosecond speeds for superior processing, the dedicated analog supply ensures these fast transitions introduce no noise into the output stage. The result is extraordinary conversion fidelity with an impressive 131 dB dynamic range and 131 dB SNR, delivering pristine clarity and exceptional micro-detail.

Equipped With 3rd Gen XMOS XU-316 Processor For High-Resolution Sound

Topping DX9 Discrete is powered by the advanced 16-core XMOS XU-316 processor, offering support for 32-bit/768 kHz PCM and native DSD512 decoding. Its high-efficiency architecture ensures fast response, stable performance, and seamless compatibility across platforms. Paired with Topping’s custom Thesycon USB driver for Windows, it maintains low latency and reliable high-resolution playback for demanding audiophile applications.

Dual-Stage Jitter Suppression & Custom I/V Conversion For Clean & Dynamic Sound

Topping DX9 Discrete employs a CPLD and precision clock system for dual-stage jitter reduction, suppressing artefacts and stabilising digital timing. Its proprietary I/V conversion, optimised specifically for the PSRM architecture, combines low-distortion op-amps with low-noise discrete components to extract maximum dynamic energy from the DAC. This allows to produce clean notes, rich textures and a more immersive presentation.

Fused With Fully Balanced Hybrid Relay Volume Control For Precise Audio Output

Topping DX9 Discrete uses a hybrid relay-resistor network to achieve precise, low-distortion volume adjustment. The design eliminates channel imbalance at low listening levels and maintains absolute accuracy across the full range. By combining mechanical relay switching with digital volume control, it improves noise immunity and delivers a more refined, stable and transparent output for headphones and speakers.

Convolution-Based Headphone Cross Feed For Immersive Listening Experience

Topping DX9 Discrete implements a convolution-based cross feed engine that accurately simulates HRTF and room acoustics to improve spatial depth and natural imaging. It reduces the “in-head” effect typical of headphone listening without flattening tonal balance. An enhanced BS2B-inspired simplified mode is also available, providing a relaxed, speaker-like presentation for listeners who prefer minimal processing.

Tailor Your Audio Needs With The Ten-Band High-Precision PEQ

Topping DX9 Discrete introduces a new 10-band parametric EQ system with custom DSP algorithms and a dedicated desktop application. Users can precisely adjust frequency, gain, and Q-factor, import target and raw response curves, and save multiple profiles. With independent EQ control for headphone and speaker outputs, the DX9 Discrete offers deep personalisation for any setup.

Various Connectivity Options To Pair Wired & Wireless Audiophile Gears

Topping DX9 Discrete supports a full suite of digital inputs including USB, IIS, AES, dual optical, dual coaxial, and Bluetooth 5.1 powered by Qualcomm’s QCC5125 chip. LDAC, aptX Adaptive, aptX HD, aptX, AAC, and SBC ensure high-resolution wireless performance. The AK4118 receiver handles SPDIF inputs with jitter as low as 50 ps RMS, offering support up to 768 kHz PCM and DSD512 across compatible formats.

Built With Panoramic Glass Top, Dual Displays & Various Premium Components

Topping DX9 Discrete showcases its precision-engineered internals through a panoramic glass top illuminated with ambient lighting. Dual 2.0-inch colour screens present playback information, FFT spectrum, or VU meters via the Aurora UI. Additional refinements include a 12V trigger, a multifunction control knob, an IR remote and a unibody CNC-machined aluminium chassis with a fine sand-blasted finish, balancing durability with modern aesthetics.
