X-Hybrid Headphone Amplifier Circuit. X-Hybrid represents a new technological breakthrough following NFCA architecture. Utilizing an all-new triple-stage hybrid amplification design, it not only retains the signature ultra-low distortion and high dynamic range of the NFCA, but also achieves significantly improved efficiency by optimizing circuit topology--resulting in reduced static power consumption and heat generation. Despite its compact chassis, it houses a fully balanced, quad-channel amplifier.. Wide range of adaptation to headphones. DX5 II is equipped with 6.35 mm single-ended, 4.4 mm balanced, and 4-pin XLR headphone jack, meeting the needs from low-sensitivity headphones to high-sensitive IEMs.
With a low noise floor of just 1.8 uVrms, even the most sensitive IEMs remain free from any audible background hiss. Delivering a powerful 7600mW x 2 output, DX5 Il allows most headphones to reach their full performance potential.. LDAC wireless available. Equipped with QCC5125 chip, DX5 II supports Bluetooth 5.1 and can support up to 96kHz/24bit. Also it fully supports LDAC/aptX-Adaptive/aptX/aptX HD/AAC/SBC and other audio encodings, allowing audio to be transmitted wirelessly to provide a music experience beyond CD level.
