The world of PC audio is rapidly expanding as the next-gen listening style. “d+ USB” which is originally designed for sound professionals also functions as the core of the digital data transmission of the PC audio. Due to the fact that there are no change of the frequency balance by cable in the data transmission, “d+ USB” delivers the clean and stable data for an USB-DAC.
The most important factor for digital is lossless, speedy and accurate data transmission. And a cable has many factors which affect sound quality and cause the errors of data transmission such as noise by electro-magnetic wave, impedance matching, and attenuation of electric signal.
Based on the basic concept of the data transmission, we put noise protection and excellent electric characteristic to the cable into practice applying our long-time experience of the cable production. “d+ USB ” was produced as a result of considering the best combination of structure, conductor, diameter, insulator, shielding, sheath and even the contact pin of the connector.
Furthermore, we especially considered the industrial design to provide the stylish appearance on your desktop.
