Features of Topping DX9 DAC NFCA Headphone amp - AK4499EQ Flagship DAC, Hybrid Relay Volume Control, 6-Channel Discrete NFCA high-Performance (Black,15th Anniversary)

?? ???????????????? ?????????????? ???????? ??????????????'?? ???????? ?????????????????????? ????????-????, the TOPPING DX9 offers an impeccable audio environment. 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. | TOPPING DX9 is powered by the rare and legendary ???????????????? ?????? ????????, 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. | ??????-?????????????? ???????????????? ???????? (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 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. | The DAC and headphone amplifier circuits in the DX9 are ?????????????? ??????????????????????????. This ensures clean, unadulterated sound by providing plenty of energy and reducing interference between the circuits.
