Flagship Design

From the isolated switching power supply modules to the panoramic sunroof, DX9 demonstrates a balance between performance and aesthetics. Get a look inside at the well-selected components and immaculately crafted board layout to appreciate the engineering and visual design of DX9.

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 bitrate.

Outstanding performance comes from a powerful core. CPLD focuses on clock processing and signal optimization. It coordinates the processing of digital signal optimization, effectively improving signal quality and stability.

Flagship Power

It 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.

The self-developed high-performance discrete headphone amplifier circuit included six independent modules. The single ended/balanced Headphone amplifier circuit is completely independent, and the use of balanced and single ended interfaces 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.
