Topping DX9 Flagship AK4499EQ DAC & Headphone Amplifier

DX9 is TOPPING's 15th anniversary commemorative model, and it is TOPPING's most powerful all-in-one product so far. It uses the AK4499EQ as the DAC chip, achieving a dynamic range of 132dB and a harmonic distortion of THD+N<0.00007%. The self-developed high-performance discrete amp circuit contains 6 independent modules, making single-ended/balanced amps completely independent and non-interfering with each other. Each module contains 39 transistors, which achieve excellent performance through precise adjustment, surpassing various similar products on the market. The amazing driving power of 7000mW x 2 @32Ω THD+N<0.00009% is enough to drive all kinds of headphones. The dual color screens are equipped with TOPPING's new Aurora UI, and the buttons and knobs complement each other. You can quickly customize settings by pressing the knob according to your habit. Full ecological interface configuration, adaptable to any listening scene. The 8-channel digital input can connect to more front-end audio source equipment at one time. The independent line out and pre-amp output can work at the same time, realizing multiple uses in one machine. DX9 is a well-deserved home music center.

Flagship DAC for the audiophile

The DX9 is powered by the rare and legendary AK4499EQ DAC chip, boasting an exceptional 132dB dynamic range and less than 0.00007% harmonic distortion. With four independent channels, it brings unmatched audio fidelity and clarity to your listening sessions. This DAC chip is like having two flagship AK4499EX chips working in tandem, and when paired with the AK4118—currently the lowest jitter S/PDIF receiver—the DX9 offers top-tier performance.

Unshakable audio quality

The six-channel discrete NFCA (Nested Feedback Composite Amplifier) high-performance headphone amplifier module packs a punch. With 7000mW of driving force per channel and distortion levels below 0.00009%, it's got the power and finesse to handle even the most demanding headphones with ease.

The fine art of volume control

The hybrid relay volume network in the DX9 is all about precision. By combining resistor and relay-based control, it greatly optimizes SNR (Signal-to-Noise Ratio) and minimizes noise at low volumes. This gives you high-precision volume control, making each decibel adjustment a deliberate choice, not a compromise.

Power independence

The DAC and headphone amplifier circuits in the DX9 are powered independently. This ensures clean, unadulterated sound by providing plenty of energy and reducing interference between the circuits.

Flagship user interface

The DX9 comes with dual 2.0-inch full-color screens and features TOPPING's new Aurora UI—intuitive, easy to navigate, and visually stunning. The knob and buttons complement each other seamlessly, making operation buttery smooth.

Flexibility in connectivity

Eight-way digital inputs including AES, USB, Optical, Coax, and Bluetooth ensure that the DX9 can connect to a wide range of devices. With independent LINE OUT and preamplifier outputs, the DX9 makes flagship performance accessible to a multitude of setups.
