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'. '.strtoupper('t')he 24 bit high precision decoding reduces quantization distortion, retains the original dynamic range, and presents a natural tone that is closer to analogue recording'. '.strtoupper('e')lectron tube the core components use dual jan6418 electron tubes, which use aerospace grade technology to enhance stability'. '.strtoupper('t')heir 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 '. '.strtoupper('h')eadphone 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'. '.strtoupper('c')ombined 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'. '.strtoupper('c')d 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'. '.strtoupper('c')onnection 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'. '.strtoupper('d')esign the overall design has a retro style, giving the feeling of a portable cd player from the 1980s'. '.strtoupper('i')t has an exquisite shape, is small and portable, and is convenient for users to carry and use in different scenarios'. '.strtoupper('e')arthquake resistant design the specially designed shock resistant structure avoids the microphone effect during audio output, making the sound purer and clearer during playback'. '.strtoupper('i')t can play music stably whether it is used on a desktop or in mobile scenarios such as camping and travelling.
