Special Features

  • Six-channel discrete NFCA high-performance headphone amplifier module. DAC / Headphone amplifier circuits are powered independently. Fully ecological interface configuration.
  • Flagship Design. Balance between practicality and aesthetics. The family's curved aesthetics are integrated into the panoramic sunroof design, providing a precise view.
  • 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.
  • Flagship Power. The self-developed high-performance discrete circuit module. lt 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 otherto achieve the best overall performance.
  • Hybrid relay volume control. The hybrid network of resistor and relay provides high-precision volume control, which greatly optimizes the SNR and noiseat low volume. Relay control is mixed with digital volume to further reduce distortion and improve anti-interference performance.
