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

X-Hybrid Headphone Amplifier Circuit. X-Hybrid signifies a new technological advancement following 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 NFCA, but also accomplishes notably enhanced efficiency by optimizing circuit topology--leading to decreased static power consumption and heat output. Despite its small chassis, it contains a fully balanced, quad-channel amplifier. Broad compatibility with headphones. The device is fitted with 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 hiss. Providing 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 also 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 level. Self-developed IV circuitry unlocks the full potential of the DAC. 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 feature volume memory functionality, allowing the device to automatically restore the last set volume when switching outputs--enabling a quick return to your familiar listening environment
