Fully carbon fibre body pushing the boundaries of what can be done, the qx13 is made with up to 21 layers of stacked carbon fibre for a lightweight yet durable build'. '.strtoupper('t')he carbon fibre also allows it to be resistant to interference and heat, while featuring a unique texture and a premium feel'. '.strtoupper('e')xtra large colour display the qx13 features an extra large colour display outfitted with corning third gen high strength glass for greater durability and scratch resistance, rare among audio dongles'. '.strtoupper('m')ultiple newly developed personalised ui themes powered by a 32 bit processor ensure that the user experience is unrivalled among audio dongles, making it just right for you, whether in portrait or landscape mode'. '.strtoupper('d')esktop grade dac flagship ess sabre pro es9027pro the chip features a fully differential audio architecture design with 8 channels set up in parallel, and is paired with a pair of ultra low noise es9312 regulators for precise output matching on each audio channel'. '.strtoupper('a')udio signals are accurately restored thanks to this pair of chips optimised power efficiency and effectiveness in reducing clock jitter'. '.strtoupper('t')he ess sabre pro series of dac chips are mainly used in high end audio systems and professional audio gear'. '.strtoupper('t')he first generation of products included the flagship es9038pro, and the second generation of products included the new flagship es9039pro and ees9027pro'. '.strtoupper('6') high end ti op amps powerful and stable output with high efficiency the qx13 uses four wafer level precision integrated ina1620 chips, with a specially designed internal layout to significantly reduce crosstalk, for no interference between channels even under extreme conditions'. '.strtoupper('a')dditionally, two low noise, low distortion opa1692 chips are employed to ensure excellent dynamics under various load conditions'. '.strtoupper('i')mage x745 patented desktop mode balancing performance and power consumption thanks to its new configuration, optimised audio circuit, and more efficient heat dissipation, the qx13 in desktop mode can deliver power comparable to full size headphone amplifiers while also significantly reducing power consumption'. '.strtoupper('i')t also features a high precision power meter, capable of accurately assessing the power supply capabilities of different usb sources and intelligently adjusting the headphone amplifiers gain and output power accordingly'. '.strtoupper('p')atent no'. '.strtoupper('z')l202321946664.8 digital and analogue separation multi layer shielding the digital and analogue boards are separated and equipped with a shielding cover for isolation, ensuring precise and dynamic signal processing'. '.strtoupper('t')his design also effectively absorbs and dissipates heat, enabling effective thermal management and ensuring the qx13 delivers sustained high power output'. '.strtoupper('x')mos 16 core xu316 the qx13 has pro grade usb audio quality, with high performance, low latency, and support of up to 768khz 32bit pcm and dsd512 native decoding'. '.strtoupper('d')ual ultra low phase noise, low temperature drift femtosecond crystal oscillators ensure that audio of various sampling rates is correctly handled for the best sound quality'. '.strtoupper('t')he xmos xu316 also allows for a 10 band lossless peq, which can be tuned either via the android fiio control app or through the web, making it easy to dial in your sound'. '.strtoupper('s')pecially designed audio architecture rivalling pro dac and headphone amplifiers the qx13 condenses audio architecture design found in fairly high end dac and headphone amplifiers into a small dongle'. '.strtoupper('t')he qx13 with its design achieves high precision conversion of audio signals to the dac thanks to dual crystal oscillators'. '.strtoupper('t')he audio signal goes through multiple stages of analogue processingmdashincluding lpf voltage amplification, buf current boosting, and parallel enhanced current expansionmdashdelivering sound quality comparable to that of professional dac and headphone amplifiers.
