Condition is like new Small but mighty The AstellKern USB-C DUAL DAC CABLE has been designed as an extension of existing AstellKern DAP lines. Smartphone manufacturers are removing headphone jacks from their products. Without a headphone jack how do you listen to music on your smartphone with the headphones and earphones you currently own? As streaming services begin to support high-quality high-resolution audio are wireless earphones and headphones able to provide the full audio playback experience? How can you enjoy high-quality music playback or games with dynamic and realistic sound on your computerwithout an expensive high-end sound card? The AstellKern development team set out to create a product that would answer these questions. Features: Full-metal housing design Dual-DAC HiFi audio chipset Silver-plated copper shielded cable Small size but powerful output Dedicated Dual DAC with Hi-Fi Ultra High-Resolution Sound The AstellKern USB-C DUAL DAC Cable features two Cirrus Logic CS43198 MasterHIFI DACs

Selling this beast of a headphone Amp Dac Pre Amp by Audio GD. This is the NFB 11-28 Jam packed with features. Comes with power cord. May show slight signs wear but presents very wellI. Items other than the Audio GD pictured ARE NOT INCLUDEDDirect from manufacturer. Fully discrete analog stages without any OPA and de-coupling caps in the signal path. Non- feedback ACSS analog amplifiers . Built with 4 pcs 20W (in total 80W) high speed Toshiba output transistors, able to drive most of the headphones out there . Total of 6 groups dedicated power circuits are used to purify the power supply. High-End grade parts built in , ALPS 27 volume pot . CMC pure copper RCA sockets ect. 3 channels digital input : coaxial / Optical / USB DAC output : RCA (User can setting with either variable level as DAC with preamp combo or fixed output level as dedicated DAC ) Headphone output : 6.3MM SE The NFB-11 applies the newest ESS high-end Sabre32 DA chip ES9028 which can support up to 32Bit/384KHz input . To be achieve the best performance of ES9028 , must work in current output mode. in voltage output model, there is -12DB THD+N loss . The standard current model design usually need 3 amps (OPA) , the first amp implements I/V conversion, the ES9028 output current signal to voltage signal . The second amp is responsible for conversion balanced signal ,to single-ended signal and implement the low pass analog filter , then go through the volume control fed to the third amp, (the headphone amp ). Every amp usually have two gain stages built in to the ES9028 chip . Signal must go through total of 6 gain stages and finally arrive at the output stage. The NFB-11 applies Non-feedback ACSS design. The ES9028 feed to the ACSS circuit without any OPAs . The ACSS circuit naturally working in current mode . The ACSS amp only have one current gain stage , the ES9028 output signal only goes through one stage . The shortest signal path can reproduce the best detail and dynamics almost without any sound coloration .It showes the real performance of the ES9028 dac. So our ACSS design is the best combo with ES9028 to achieve the best performance .

The company has been making digital audio players since its founding in 2013. In that time, A&Ks engineers have created a detailed, accurate signature sound that can be found across all their offerings, including this one. The Dual DAC Cable makes a high-res experience truly portable with its compact size, two 32-bit digital-to-analog converter chips, custom-made cables and electronics, and a clean, powerful headphone amplifier. Its also an eye-catcher - it uses the same light and shadow design concept their digital audio players employ, with striking, smooth edges and a polished finish. What makes it tick? The twin Cirrus Logic CS43198 DAC chips inside are real workhorses. They independently process the left and right channels to keep soundstage spacious and detailed. Astell&Kern chose them because they deliver an efficient audiophile-grade sound, meaning they dont sacrifice a lot of your phones battery life for performance. The chips have a warm sound that helps to give life and energy to the music pumping through them. A&Ks engineers also tweaked the chips digital-interpolation filters to get the sound just right. A deeper look at whats inside The company is a master of circuit design. Youll not only find the two DAC chips I mentioned on the small, six-layer PCB (printed circuit board), but also Astell&Kern-exclusive micro resistors and tantalum capacitors. Those help to optimize the audio circuit and suppress power fluctuations, giving you stable operation and superb sonic performance. A durable, noise-killing cable A DAC like this is only as good as its cable. A&K ran with that idea and made this DACs cable top-shelf. The custom-made, durable, four-core cable was built to block out noise. ABOUT SKY BY GRAMOPHONE SEE IT. HEAR IT. LIVE IT.

I am the second owner of this device. Bought it from original owner in 2019 and has been my daily driver ever since. The device is in great working condition and overall is well-maintained. Will come with power and USB cable. As shown last couple pictures: 1) Minor scratch on bottom surface not visible during use 2) Barely visible hairline scratches on volume knob - really have to play around with the lighting and angle to catch it Note: requires 1/4” end to connect to DAC/AMP
