Topping DX5 II Decoder Dual ES9039Q2M Desktop DAC & Headphone Amplifier (Black)

X-Hybrid Headphone Amplifier Circuit. X-Hybrid signifies a fresh technological advancement based on the NFCA architecture. Employing a completely new triple-stage hybrid amplification design, it not only maintains the characteristic ultra-low distortion and high dynamic range of the NFCA, but also attains notably enhanced efficiency by refining circuit topology--leading to decreased static power consumption and heat output. Despite its small form factor, it contains a fully balanced, quad-channel amplifier. It provides a broad range of compatibility with headphones. It features 6.35mm single-ended, 4.4mm balanced, and 4-pin XLR headphone jacks, catering to needs from low-sensitivity headphones to high-sensitivity IEMs. With a low noise floor of merely 1.8uVrms, even the most sensitive IEMs stay clear of any audible background noise. Supplying a robust 7600mW x 2 output, it enables most headphones to realize their full performance capability. LDAC wireless is supported. Fitted with a QCC5125 chip, it supports Bluetooth 5.1 and can handle up to 96kHz/24bit. It fully supports LDAC, aptX-Adaptive, aptX, aptX HD, AAC, SBC and other audio codecs, allowing audio to be transmitted wirelessly to deliver a music experience surpassing CD quality. A self-developed IV circuit unlocks the complete DAC potential. The self-developed I/V conversion module is focused on achieving superior audio reproduction. The outstanding circuit design provides lower distortion and noise while taking up less space. Pushing the boundaries of physical limits, this design extracts the maximum performance from the DAC chip. Directly connect an active speaker to adjust volume. It also includes a "preamp" mode. In preamp mode, you can adjust the output volume, then connect it directly to a pure amplifier or active speaker without requiring a separate preamplifier. Both input and output interfaces come with volume memory functionality, enabling the device to automatically restore the last set volume when switching outputs, allowing for a swift return to your familiar listening environment
