Topping DX5 II Dual ES9039Q2M

Dual ES9039Q2M DACs for Superior Audio

The DX5 II features two high-performance ESS ES9039Q2M DAC chips—one dedicated to each audio channel. This fully balanced architecture delivers significantly improved signal-to-noise ratio (SNR), dynamic range (DNR), and reduced distortion compared to its predecessor, the DX5, enabling exceptional high-resolution audio playback.

X-Hybrid Headphone Amplifier Circuit

Introducing the next evolution of NFCA technology, the X-Hybrid amplifier circuit. Utilizing a brand-new triple-stage hybrid amplification design, it retains the ultra-low distortion and high dynamic range characteristics of NFCA while enhancing efficiency and reducing power consumption and heat. Despite its compact form factor, the DX5 II integrates a fully balanced, quad-channel headphone amplifier.

Versatile Headphone Compatibility

With 6.35mm single-ended, 4.4mm balanced, and 4-pin XLR outputs, the DX5 II accommodates everything from ultra-sensitive IEMs to high-impedance headphones. Thanks to an ultra-low noise floor of just 1.8μVrms and up to 7600mW x 2 output power, it ensures clean, powerful performance across the board.

Aurora UI with Full-Color Display

Navigate your settings effortlessly with the 2.0-inch full-color screen and three-button control layout. Choose from nine customizable background colors and display modes (FFT, VU meter, or playback info) to match your aesthetic. The pressable knob supports assignable functions, letting you switch output modes and tailor your listening experience with ease.

Precision PEQ Adjustment

The DX5 II debuts TOPPING’s brand-new 10-band PEQ system, offering high-precision tuning of frequency, gain, and bandwidth for each band. With PC software support, users can import target curves, apply curve compensation, and save multiple presets. Independent PEQ profiles for headphone and line-out outputs allow you to dial in the perfect sound for any setup.

Wireless Hi-Res Audio via Bluetooth

Powered by a QCC5125 chip, the DX5 II supports Bluetooth 5.1 with high-resolution wireless audio transmission. Enjoy playback up to 96kHz/24bit with full support for LDAC, aptX Adaptive, aptX HD, aptX, AAC, and SBC—delivering a wireless listening experience that rivals wired fidelity.

Plug & Play with Broad OS Support

Compatible with Windows 10/11, macOS, Linux, iOS, and Android, the DX5 II features a third-gen XMOS XU316 USB interface with Thesycon drivers for stable and high-performance operation. USB input supports up to PCM 768kHz/32bit and DSD512, ensuring every detail is captured in your digital library.

Self-Developed I/V Conversion Circuit

A custom-designed I/V conversion circuit maximizes the performance of the dual DAC chips. By minimizing distortion and noise in a compact footprint, this circuit unlocks the full potential of the ES9039Q2M.

Direct-to-Speaker Preamp Mode

Activate preamp mode to control volume directly from the DX5 II when connecting to a power amplifier or active speakers—no external preamp needed. With volume memory for each input/output configuration, your listening settings are always just where you left them.

12V Trigger for System Integration

The DX5 II includes 12V trigger input and output ports, allowing it to power on or off in sync with other compatible devices, for seamless system integration.
