Flagship Chipset

Outstanding performance comes from a powerful core. The rare and legendary DAC chip AK4499EQ powers the DX9 to achieve 132dB dynamic range and THD+N <0.00007% harmonic distortion. The AK4499EQ has four independent channels, which is equivalent to the performance of two flagship AK4499EX.

The AK4118 receiver is currently the lowest jitter S/PDIF receiver. It is compatible with optical fiber, coax, and AES reception, and supports up to 24bit/192kHz frequencies. CPLD focuses on clock processing and signal optimization. It coordinates the processing of digital signal optimization, thus effectively improving signal quality and stability.

The Bluetooth chip adopts QCC5125, supports Bluetooth protocols: LDAClaptX/aptX adative/aptX-HD.

Flagship Power

The DX9 achieves incredible low distortion with 39 transistors per module, surpassing all kinds of discrete and integrated headphone amplifier circuits on the market. Multi-modules can cooperate with each other to achieve the best overall performance.

  • Six-channel discrete NFCA high-performance headphone amplifier – The self-developed high-performance discrete headphone amplifier circuit included six independent modules. The single ended/balanced Headphone amplifier circuit is complete- ly independent, and the use of balanced and single ended interfac- es does not interfere with each other, further reducing distortion and noise. The amazing driving force of 7000mW x 2 @32Q THD+N<0.00009% is enough to drive all kinds of hard-to-push headphones and drive them to the proper level.
  • Hybrid relay volume control – The hybrid network of resistor and relay provides high-precision volume control, which greatly optimizes the SNR and noise at low volume. Relay control is mixed with digital volume to further reduce distortion and improve anti-interference performance. The DAC/Headphone amplifier circuits are independently powered, providing plenty of energy and ensuring the purity of sound. One is all.
Flagship Application

The dual color screen is equipped with the new Aurora UI of TOPPING, which is convenient to set up and experience freely. Dual 2.0-inch full-color screen equipped with Aurora UI, which supports playing information, FFT and VU switching display. The button and knob complement each other, and you can quickly customize the settings by pressing the knob according to your habits, bringing a smooth operation

DX9 has independent LINE OUT and preamplifier output, and its XLR interfaces all adopt NEUTRIK, so the flagship performance is within reach.

Eight-way digital inputs such as AES / USB / Optical * 2 / Coax * 2 / IIS/ BT allow all your devices to connect to DX9.

The 12V Trigger linkage switch can switch multiple devices with one key.

Balance between practicality and aesthetics

The family’s curved aesthetics are integrated into the panoramic sunroof design, providing a precise view.

Dedicated Remote Control

The main body of the chassis is CNC machined from a single piece of high-strength aluminum alloy and undergoes fine sandblasting.
