• AK4499EQ DAC Chip : The DAC chip AK4499EQ powers the DX9. The AK4499EQ has four independent channels, achieving 132dB dynamic range and THD+N <0.00007% harmonic distortion • AK4118 Receiver : The DX9 has a built-in AK4118 receiver, which is currently the S/PDIF receiver with the lowest jitter. It is compatible with fiber optic, coax and AES reception and supports frequencies up to 24bit/192kHz • Eight Digital Inputs : The DX9 has 8 digital inputs including USB/AES/IIS/Bluetooth/optical*2/coaxial*2. Adaptable to a variety of setups and applications to meet all your audio needs • Six-channel Discrete NFCA : Six built-in high-performance discrete headphone amplifier circuits further reduce distortion and noise. The amazing driving power of 7000mW x2 @32Q THD+N<0.00009% is enough to drive all kinds of hard-to-recommend headphones • Unique Appearance Design : The DX9 adopts a panoramic sunroof design to provide an unobstructed view, and dual 2.0-inch full-color screens equipped with Aurora UI, which supports playback information, FFT, and VU switching display
