Celebrating 15 Years of Superior Sound with the TOPPING DX9

Introducing the TOPPING DX9, a special edition DAC and headphone amplifier marking 15 years of TOPPING's excellence in audio engineering. As a highlight of their 15th Anniversary collection, the DX9 is a leader in the market, not just a participant. It features the cutting-edge AK449EQ DAC chipset, a unique hybrid relay volume control, and a six-channel discrete NFCA (Nested Feedback Composite Amplifier) for high-performance headphone amplification, creating an unparalleled audio experience.

Advanced DAC for Audiophiles

The heart of the DX9 is the prestigious AK4499EQ DAC chip, renowned for its extraordinary 132dB dynamic range and minimal harmonic distortion below 0.00007%. This chip, equivalent to having two flagship AK4499EX chips in parallel, together with the AK4118 - the lowest jitter S/PDIF receiver available - propels the DX9 into the upper echelons of audio performance

Exceptional Audio Quality

The DX9's six-channel discrete NFCA headphone amplifier module delivers a powerful 7000mW per channel with distortion under 0.00009%, making it adept at driving even the most demanding headphones. The independent power supplies for the DAC and amplifier circuits ensure a pristine, interference-free sound.

Precision Volume Control

The hybrid relay volume network in the DX9 sets a new standard for precision. This design, merging resistor and relay-based control, optimizes SNR and reduces noise at lower volumes. The result is a finely-tuned volume adjustment, enabling precise control over each decibel.

Innovative User Interface and Connectivity

The DX9 comes with dual 2.0-inch full-color screens featuring the intuitive Aurora UI, for easy and visually pleasing navigation. The seamless integration of its control knob and buttons makes for a fluid user experience. Its array of connectivity options, including AES, USB, Optical, Coax, and Bluetooth, along with independent LINE OUT and preamplifier outputs, ensures that the DX9 is versatile and adaptable to various audio setups.
