Decoding technology It adopts Shanling's self-developed Kunlun 24-bit R2R DAC architecture, uses an R-2R resistor network to replace the traditional Delta-Sigma chip, and directly realizes digital signal conversion through a precision resistor array. The 24-bit high-precision decoding reduces quantization distortion, retains the original dynamic range, and presents a natural tone that is closer to analogue recording. Electron tube The core components use dual JAN6418 electron tubes, which use aerospace-grade technology to enhance stability. Their unique even-order harmonic distortion characteristics add a soft sense of air and overtones to the sound, while taking into account both Hi-Fi fidelity and "tube flavour". Headphone amplifier chip Equipped with Texas Instruments' high-performance headphone amplifier chip TPA6120, it has extremely low output impedance and ultra-high current driving capability, and can easily control high-impedance headphones. Combined with a low-noise power supply design, it ensures a pure background under large dynamics and sharp transient response, giving the music surging energy and delicate micro-dynamics. CD Reading System It adopts active magnetic pressure and abandons the card-bead-type mechanical fixation, and locks the disc firmly with balanced adsorption force to eliminate scratches and disc reading deviation; it is equipped with a professional CD solution movement and a customized servo system to dynamically optimize the disc reading trajectory in real time, improve the disc reading performance and response speed; the alloy motor uses rare metal palladium-plated brushes and has undergone thousands of hours of rigorous testing to ensure power and stability under high load; each device undergoes dozens of hours of multi-dimensional adjustment before leaving the factory to achieve industrial-grade assembly precision. Connection Mode It supports Bluetooth high-definition transmission to achieve wireless connection and playback; it has USB DAC decoding function to meet users' needs for digital audio conversion; it provides single-ended and balanced dual output modes, and is compatible with more headphone options, whether it is high-impedance headphones or low-impedance headphones, it can fully demonstrate its due sound quality. Design The overall design has a retro style, giving the feeling of a portable CD player from the 1980s. It has an exquisite shape, is small and portable, and is convenient for users to carry and use in different scenarios. Earthquake-resistant design The specially designed shock-resistant structure avoids the microphone effect during audio output, making the sound purer and clearer during playback. It can play music stably whether it is used on a desktop or in mobile scenarios such as camping and travelling.
