TOPPING DX9D/BK DAC

TOPPING DX9｜Flagship Fully Balanced Discrete 1-Bit DAC Headphone Amplifier

An Acoustic Masterpiece, an All-in-One Solution for the Ultimate Audiophile

The TOPPING DX9 is a flagship fully balanced DAC headphone amplifier, featuring TOPPING's self-developed 1-Bit DAC PSRM discrete architecture with 16 independent components per channel, combined with a powerful six-channel discrete NFCA headphone amplifier module. Its astonishing 7080mW x 2 @32Ω balanced output power effortlessly drives any difficult-to-drive flagship headphones on the market, offering unparalleled control and dynamic performance.

Compared to traditional designs using off-the-shelf DAC chips, the TOPPING DX9's discrete 1-Bit PSRM architecture provides a purer digital-to-analog conversion, closer to the original signal, achieving an unprecedented 132dB Dynamic Range and less than 0.00007% total harmonic distortion, delivering an ultimately clean and detailed listening experience.

TOPPING DX9 Core Technologies and Features

• Self-developed 1-Bit PSRM Discrete DAC Architecture: Not using off-the-shelf DAC chips, the DX9 features TOPPING's self-developed 1-Bit PSRM (Pulse-Space Ratio Modulation) DAC, composed of 16 high-precision resistor components per channel, achieving an ultimate 132dB Dynamic Range and pure, uncolored sound quality.
• Fully Balanced Independent Circuit Design: From the DAC to the headphone amplifier module, each channel of the DX9 employs a completely independent balanced circuit design, effectively eliminating crosstalk interference and ensuring excellent channel separation and pure audio fidelity.
• Six-Channel Discrete NFCA Headphone Amplifier Module: Equipped with a newly designed discrete NFCA (Nested Feedback Composite Amplifier) headphone amplifier circuit, it delivers a powerful output of up to 7080mW x 2 @32Ω while maintaining an Output Impedance below 0.1Ω, effortlessly driving various high and low impedance headphones.
• Hybrid Relay Volume Control: Combining resistors and a relay network, it achieves extremely precise volume control. This design not only ensures perfect left and right channel balance at any volume but also avoids distortion that traditional potentiometers might produce.
• Professional Ten-Band Parametric Equalizer (PEQ): Built-in high-precision ten-band PEQ allows for fine adjustment of each frequency band via computer software, including frequency, Gain, and Q values, enabling you to tailor a unique sound curve according to different headphones or personal preferences.
• Advanced Crossfeed Soundstage Processing: Utilizing convolutional computation technology, it simulates a natural speaker listening experience, reducing auditory fatigue from prolonged headphone use, and creating a more open and realistic sense of space and soundstage localization.
• Rich Digital Inputs and Bluetooth Support: Equipped with multiple digital input interfaces such as USB, IIS, AES, Coaxial, and Optical, and supporting high-resolution Bluetooth codecs like LDAC and aptX HD, it meets your needs for connecting various audio sources.
• Flagship Craftsmanship and Dual Screen Design: Featuring a CNC precision-machined aluminum alloy body, paired with a tempered glass top cover and dual full-color screens, it not only provides clear information display but also showcases the excellent texture and design aesthetics of a flagship product.
